Well first I was trying to walk back to my bedroom but he kept getting in my way. Then he comes into my bedroom when i'm talking to a friend one the phone (It was a girl) and my brother runs in there, takes the phone away from me and says "He likes you!" and to top it all of I we had to fold the laundry and he left to go somewhere with his friends and left me to do all the laundry! So... I had good reason for punching him.
