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.
Two characters, strangers or hostile to each other, accidentally discover a common thing. It can be an interest, or 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

- Eliza attempts to invoke this twice on Selfie:
- In "Un-Tag My Heart" she expresses how much she has in common with her neighbor Bryn, when they obviously don't. Eliza tries to form an interest in Bryn's book club, (and avoid just thinking about sex with her current partner), but it doesn't work out when another member of the group points out Eliza's bookmark is eight pages in.
- Eliza also does this in "With a Little Yelp From My Friends", by stalking co-worker Joan's reviews (after failing to find anything about her on things like Facebook, Instagram, and Twitter) of places online.

Then it gets double subverted when he reveals that he actually fought on Guadalcanal where the American also served during the war and was injured.
