You are in a relationship with the love of your life! You and said love are happy as can be and [[FamousLastWords nothing can go wrong]]!

[[TemptingFate Then it does]].

And you hate the world. Especially since the world seems to be mocking you for it. As you walk through the park, EVERYONE is paired up. You see couples on the benches, making out, couples on the lake, making out, couples under trees, [[RuleOfThree making out]], even the birds and frogs and PLANTS seem to be paired up with their life-long partner, and you're not. The world is mocking you.

If this is a musical, then this scene usually involves a very sad song. In a romantic comedy, the scene may go to extreme lengths to show the pair ups, and the scene will come after the SecondActBreakup and before the reconciliation.

This trope can be PlayedForLaughs or PlayedForDrama. Also, it doesn't have to be about romantic breakups - it can also be used when someone has died or gone missing, or some highly emotional object has been lost through no fault of their own. In these instances, expect the protagonist to mistake other people or objects for the one they lost.

Look for LonelyPianoPiece in visual examples.

The romantic version is a subtrope of AloneAmongTheCouples.

Somewhat TruthInTelevision in that those who have recently lost something will tend to notice these things a LOT more than someone who hasn't suffered such a loss.

Compare ColdTurkeysEverywhere, wherein that trope is for people who willingly gave up something, and the world is tempting them constantly. Compare/Contrast SpontaneousChoreography. Contrast YouAreNotAlone.

[[AC: Anime and Manga]]
* ''[[Manga/MidoriNoHibi Midori no Hibi]]'' does this to Seiji several times in both the anime and manga versions:
** In the first chapter of the manga, he becomes depressed after striking out with a local girl, only to find himself surrounded by lovey-dovey couples on his way to school... [[ he doesn't take it well.]]
** And, in chapter 17, he ends up alone in [[ a cafe full of happy couples.]]
** The anime version has him strike out with the same girl from the first example, after which, he goes to a movie theater to sulk. When he realizes he's the only one there without a date, [[Funny/MidoriNoHibi he vents his frustration on the crowd]] and storms out.

* When the eponymous ''GrooTheWanderer'' thought his dog Rufferto was dead [[spoiler:and that Groo had eaten him]] he kept seeing objects that reminded him of Rufferto's coloring.

* In ''[[Literature/ThursdayNext Lost In a Good Book]]'', Thursday starts seeing infants everywhere en route to her physician's office; she fears she's lost her pregnancy when she realizes Landen has been eradicated.

[[AC: Live-Action TV]]
* In an episode of ''LizzieMcguire'', all of the protagonists are single, but that doesn't stop them noticing that all of their classmates aren't.
-->'''Gordo:''' Everybody's paired's like Noah's ark.

* In ''BetterOffDead'', Lane is constantly reminded of his ex, Beth, because every other guy in town (and Barney Rubble) wants to date her.

* The "Scotty Doesn't Know" song in ''EuroTrip''. The song was written to brag about how Scotty's girlfriend was cheating on him with the singer. [[KickTheDog They break the news to him by performing it at his graduation party]], after which the song becomes a smash hit, RunningGag, and given the name of this film, a literal example of the world mocking his loss.

[[AC: VideoGames]]
* In ''VideoGame/FinalFantasyVI'', Celes is this trope embodied for Locke.
* A large source of angst for [[JerkassWoobie Ragna the Bloodedge]] from ''VideoGame/{{Blazblue}}'': he can't go far without coming across clones of his kidnapped and missing sister.
* PlayedForLaughs in the ''{{DJ Max}}'' series, where realizing The World Mocks Their Losses is the StartOfDarkness for the [=NB=] Rangers. A group of single, unlucky average joes transform into a {{Jerkass}} SuperSentai parody once they get fed up seeing other happy couples in the park and proceed to [[AntiLoveSong attempt to ruin them or just plain beat them up]].

* In ''Disney/TheLionKing'': Simba's Pride, the scene after Kovu gets exiled is this, complete with song "Love Will Find a Way".
* ''TheSimpsons'', after Ned lost his wife he sees couples dancing and having fun at the [[FictionalHoliday Jellyfish Festival]].
-->Marge: Poor Ned. This is his first Jellyfish Festival alone.
-->Homer: I know. And it doesn't get any easier from here. There's the Tongue-Kissing Festival, Cinco de Ocho, the Hobo Oscars, days just made for lovers. Not widowers... lovers.
** In the episode with Homer buying a handgun, he is dismayed when he learns that the registration process will take a few days. He spends those days moping on his lawn. A montage of tempting targets pass by during those days: a line of ducks, a Target truck, Patty and Selma on a bike...
* [[ParodiedTrope Parodied]] in the {{Futurama}} [=DVD=] Movie "The Beast with a Billion Backs"; right after Colleen and Fry break up, Fry sees increasingly [[CrackPairing comically unlikely coupling scenarios]].

[[AC: RealLife]]
* People who have often lost someone dear to them, by death or otherwise, will often be reminded of it constantly, if nothing else because of a natural inclination towards nostalgia, and [[EpilepticTrees reading into things]] that remind them of that person. Talking to someone who just lost someone through death can lead to some especially strange metaphors. The truth is, of course, they're constantly thinking about their loss, so it's not that everything reminds them, it's that they insert the lost person into everything else: "My mother bought me this game," "My wife and I saw this movie together," which they may not remember ''every'' time they boot up that game or watch that movie. Even going into predictions like "My brother would've loved this song." becomes common for grievers.
* It goes without saying on this site that friends, family and romance are HUGE parts of fiction. It's virtually impossible for a lonely person to peruse fiction of any kind without being subjected to this. The HaremGenre anime that you find hilarious could be torture to the romantically unlucky.
