I got into a fist fight with my half brother last year. He is about my size and is 4 years younger than me. His dad was huge so he is growing a lil faster than i did. Long story short he tried to show off in front of a girl I tried to shake it off but he kept at it. I pushed him he swung so I uppercutted his ass. It felt good and I would do it again, he is spoiled rotten.
