So I'm looking for a fic I read a while ago.
It was set in either a high school or a boarding school (pretty sure it was the latter) and Tony was, of course, younger than everybody else and tended to get bullied so he hid from the people who bullied him, mostly under tables. Rhodey (or Steve) is walking along one day and hears a kid crying and finds Tony hiding. Tony, being Tony, denies the fact that he is crying but Rhodey/Steve isn't the type of person to leave a little kid when he's upset, so they end up being friends.
Sorry that it isn't much to go on. Hope I can read it again.
