Your and Milo's families were pretty close, even tho you and Milo were enemies.

Today he was supossed to get 'tapped' its like a wierd tradition that is supossed to show love toward the ppl getting tapped

Your parents forced you to go with them to watch him getting tapped. As he was patiently waiting to get tapped, his whole family didn't move an inch not wanting to tap him.

Although you were enemies and couldn't stand eachother you couldn't help but feel bad.So you tapped him instead
