- You can always depend on the kindness of strangersTo pluck up your spirits and shield you from dangers.Now here's a tip from Blanche you won't regret.A stranger's just a friend you haven't met!
The tendency of fictional works to assume that characters can talk to, share a room with, or travel with complete strangers without doing a background check or even a basic spot check - and despite this, nothing bad will ever happen. Most common in P&P roleplaying, where common sense may be handwaved in order to get to start the adventure.
In stories where this trope applies, it's usually a near unheard of and an unspeakable crime to actually lull someone into a sense of security and rob them blind. Doing so in such a story is sure to send the character straight over the Moral Event Horizon. Why else would it be pounded into most of the children of Real Life that talking to complete strangers is usually bad?
A Justified Trope, as in ancient Greece, accepting aid from and giving aid to complete strangers was shown to be a virtuous characteristic. Even in relatively recent times and stories it was not improbable for these sorts of events to occur; strife at them is likely to be due to Values Dissonance.
When this trope is in play, Walking the Earth may become easier.

- In Fire and Hemlock, this is played totally straight; the only people who actively seek to harm Polly are those who know who she is. She gatecrashes a funeral, pretends to be part of the (large) family, and befriends an adult man, who helps her get out of the party before people notice she isn't family. Sounds dangerous? Only becomes dangerous because his enemies are now her enemies.
- In Moby-Dick, Ishmael isn't put off by having to share a bed with a complete stranger, until he discovers the stranger in question is a Wild Samoan. Note that that was how inns and guest houses worked back then. A bed to yourself was very, very expensive. It only gets truly homoerotic when they start spooning and Queequeg insists on grasping his harpoon all night.
- Ayla and Jondolar from the Earth's Children series are constantly meeting new people, who are (almost) always helpful and friendly.
- In Lonely Werewolf Girl Moonglow and Daniel take in werewolf Kalix no questions asked, even when they know she is a werewolf with self destructive tendencies, no social skills, and hunted by, well pretty much everyone.
- In Galaxy of Fear, Force-Sensitive Tash Arranda gets feelings around some people. Some of the people she meets, she just feels like she can trust, though sometimes she has to struggle with whether she should or not. Most of these people are the Heroes of Other Stories, like the Heroes of Yavin, Wedge Antilles, Lando Calrissian et cetera. It gets to the point where her companions just sort of shrug and assume anyone she likes will be helpful and valorous. However, she can't always sense if someone isn't trustworthy, so if they are a Bitch in Sheep's Clothing she will assume the best, which her companions also fall afoul of.
- Explicitly averted with The Wheel of Time. The merits and shortfalls of playing one's hand close to the chest are closely examined, but there are a lot of bad people in their world.
- In the Hurog duology, this trope is sometimes subverted (Ward's younger brother ran away from the man Ward sent him to live with, because he didn't trust Ward, and thought strangers to be the safer option. Ward is perfectly trustworthy.), but also played straight a number of times - which this is justified by the number of scheming nobles. Random strangers are more trustworthy if a large number of people wants you dead because of who you are.
- Happens all the time in Highway to Heaven. After meeting Jonathan (the angel) and Mark (his sidekick), people rarely suspect any danger of any kind from these two. In one rare instance (in the episode Monster) where a boy does distrust strangers, the episode is about tolerance of those who are diffent. The boy turns out to be a liar who can't be trusted. Within a day or two of knowing someone Mark and Jonathan will be granted full access to loved ones and personal property beyond what a normal person would trust his own spouse or children to do. In some episodes, Jonathan has convinced near complete strangers to:
- Let him live in their houses.
- Cash in their entire life savings - and hand the cash over to him - to bet on a horse race!
- Take out a mortgage on their homes - and hand it over to him - to invest in the stock market.
- Take his word for it when a loved-one is sick or missing. Most people are satisfied with, "I think I know where to find him," or "You're just going to have to trust me." Never mind that Johnathan is a drifter with no ID and a new job in every episode.
- Played straight in The Odyssey, where many characters take care of main hero Odysseus.
- Both Pokémon Mystery Dungeon games start in this manner. The first game is particularly jarring, as you, a complete stranger, are tasked to rescue a baby Caterpie.
- Subverted in the second game, where a Drowzee kidnaps Azurill.
- In The Legend of Zelda, many fans have commented on Link's ability to just walk into anyplace. Few NPCs will care that much about you breaking pots and taking the goodies inside, or just walking around. Bedrooms aren't off-limits. Some places can only be entered during the day, though. This is especially apparent in Breath of the Wild, where you can talk to people for the first time while they're sleeping in their beds and they won't react as if you've snuck into their homes.
- An aspect of this fits into the general aspect of hitchhiking and picking up hitchhikers. Hitchhiking was once considered a perfectly reasonable way for young people to travel, and it was considered bad hospitality to not pick up stranded travelers along the way. Now, the general feeling is to lock one's doors; both the hitchhikers and the drivers expect the other to be scumbags who will take advantage of them, attack them, or take advantage of them and then attack them.
- This is an example where the trope feeds on itself. As hichhiking has gotten to be less respectable, fewer and fewer "nice" people were willing to pick up hichhikers, which meant that it became even more dangerous and less respectable, feeding the cycle.
- Many an older person will tell you that you didn't have to be as careful a few decades ago as you do now, but it's hard to know if that's the Nostalgia Filter talking if you weren't there.
- Also depends on country. There are countries where it is more common, and thus safe, and countries where it's less so.
- Truth in Television: If you are not a criminal, and usually stay out of conflict, the person most likely to murder you is your spouse. It's the same for rape, with the majority of offenses being date rape. It's not so much the fact that strangers are nicer people, that would be Insane Troll Logic, but due to psychological phenomenons, you could actually be safer around a random stranger than someone you are attracted to, or who approached you. note Many a parent will agree that they have no problem with their child talking to complete strangers, like the lady behind the library counter or such, but would be very wary of someone who approaches the kid on the way home from school and introduces himself properly.
