I return things I borrow. But in grade school somebody 'gave' me a toy which I kept for days until probably their parent complained and I gave it back.

Kids don't understand give and borrow.

Anyway I think my friends still have each other's things. It's hilarious because they'll just hold on to it for years and years (like books and the like)

Did I lend my friend my Kevin Smith batman books? I still need to do that. Ohoho I might never see them again!
