Commonality Connection

Go To

Once in a hotel dining-room, I said, rather too loudly, "I loathe prunes."
"So do I," came an unexpected six-year-old voice from another table.
Sympathy was instantaneous. Neither of us thought it funny. We both knew that prunes are far too nasty to be funny. That is the proper meeting between man and child as independent personalities.
C. S. Lewis, "On Three Ways of Writing For Children"

Two characters, strangers or hostile to each other, accidentally discover a common thing. It can be an interest, a past experience or a background, but it foments friendship between them. For dramatic purposes, this is often between extremely different characters.

It can also mark the deepening of an existing relationship.

Lies can sometimes backfire when another character thinks it's this trope; see I Am One of Those, Too.

Compare Fire-Forged Friends; note that merely finding they were both soldiers or the like is this, though if they fought in some of the same battles, it may shade into that. For much more extensive commonalities, see Birds of a Feather. Also compare Lonely Together.

Contrast "Not So Different" Remark and Opposites Attract. Supertrope of Bonding over Missing Parents and A Shared Suffering. The lack of this drives Joins to Fit In. Examples that do not precede a friendship may go under The One Thing I Don't Hate About You.

    • Played for Laughs in "Lemon of Troy," which involves the rivalry between Springfield and neighboring Shelbyville. Everyone in Shelbyville seems to be an Expy of a Springfield resident, and Milhouse's counterpart is also named Milhouse.

  • She-Ra and the Princesses of Power: Besides their intellectual affinities, Entrapta and Hordak bond over their rejection trauma. Hordak was sent to die in the front lies by Horde Prime because of his degeneration caused by a genectic flaw. Entrapta was convinced by Catra that the princesses left her to die in the Fright Zone which she finds believable given that she always had trouble interacting with others. The point is the princesses weren’t much nice to Entrapta, just tolerating her because they needed her knowledge in technology. So, Entrapta had good reasons to believe she had been abandoned.
  • In the South Park episode "Chef Goes Nanners," Cartman and Wendy have to work together on a school assignment. Though he's initially lazy and she's irritated in him, they wind up bonding over the fact that they eat their Oreos the same way. The episode ends with Status Quo Is God, though, thanks to Wendy kissing Cartman to end the UST and they actually get more antagonistic to each other in later seasons.
  • In the SpongeBob SquarePants episode "Boating Buddies", Squidward explains to Mrs. Puff that the reason he's taking boating school is that he was trying to avoid SpongeBob, and refers to him as the bane of his existence.

  • Squirrel Boy: In an attempt to play along Kyle's revenge scheme, Salty Mike pretends to be friendly with Andrew. It becomes legit when the parrot realizes that Andrew collects rocks that look like Snack food, a hobby he also shares. Rodney and Kyle aren't happy about this, but given the nature of the show, their friendship ends to keep the Status Quo in check.
  • Star Trek: Lower Decks: In "Moist Vessel", after Lieutenant O'Connor admits that he's a jerk for pretending to be someone he's not just so that others would think he was unique and interesting, Ensign Tendi instantly latches on to the trait that they share in common.
    Tendi: We're both jerks! We wanted to be liked and lied about it. I think that means we're best friends!

    Real Life 
  • C. S. Lewis recounts in Surprised By Joy when he went to visit a sick neighbor when he was a boy. He didn't even remember why, but when he was there, the other boy had a book of Norse Mythology. When Lewis exclaimed "What, you like that too?", they spent the rest of the visit poring over the book and forming a steadfast friendship.
  • Psychologists found that in an experiment where people could punish their partners for errors, if you told the people that the (invisible) partner had a thumbprint that was classified in the same group as them, they would punish this partner less. Even if the person doing the punishing was a textbook narcissist.
  • Starring together on Star Trek: The Original Series, William Shatner and Leonard Nimoy became friends in no small part thanks to learning they were both Jewish (Nimoy had an Orthodox Jewish upbringing, Shatner had a Reform Jewish upbringing). Through various ups and downs, their friendship lasted almost 50 years.
  • Cops who play the "Good Cop" in interrogation will often start off "befriending" the suspect by chatting with them about sports, etc., or claiming to understand their feelings of anger towards the victim. Many suspects will inevitably slip up.
  • Similarly, this is a tactic used to survive being held hostage or taken prisoner by enemy soldiers. Enforcing your humanity to them to elicit sympathy and sharing similarities such as children you both have or even mutual interests makes it harder for them to mistreat you since they begin to connect with you on a personal level and no longer merely see you as "prisoners." Even something as simple as looking a gunman in the eye makes it more difficult for them to shoot you by evoking this.
