That one time Superboy cried because Robin wouldn’t accept his birthday present for him…

Kara [about Jon]: Well, Damian, you are his best friend. Friends give each other presents.

Damian: I accept your premise; I reject your conclusion.

Tim [to Kara]: *whispering* Try telling him it’s a non-optional social convention.

Kara: What?

Jason: Just do it.

Kara [to Damian]: It’s a… non-optional social convention.

Damian: Ah. Fair enough. *takes the gift and walks away*

Dick: *grins* He came with a manual.
