My little brother and I used to go at it all the time. He has my stepdad's blood in him, so that made him a little rowdy. He even got more whippins than I did because he was so rowdy.
I remember a few years back, we were playing DBZ Budokai 2, and he got mad because I was winning. He punched in my side, I hit him back hard on the head, and he starts crying. My mom came in to see what the commotion was and I thought I was going to get in trouble. I told her that he hit me for no reason, and she essentially told him "Don't throw no blows you can't take".
After I left for college, he started to mature and we became closer. Now he's like my best friend. When ever I'm in town, he's my Alphonse Elric and I'm his Edward Elric (mostly because he's gotten a little taller than me).
