"So do I," came an unexpected six-year-old voice from another table.

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.
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.
