Today I was fooling around with my friend in the cafeteria and he pushed me so I pushed him back a little harder(I workout) and he flew and hit a girl with his elbow in the mouth.She was bleeding (not hard, a few drops). She didn't start to cry but just laughed(prolly nervous).My question is should I have apologised or even number closed(or better yet not). I saw the girl for the first time and shes old as me (19).The worst thing she was cute and I was cracking up all the time.
