my brothers are 14 and 9 or 10, i forget...and they always hit each other and stuff, never really major stuff, just like a hit and then the other yells and he chases him and he laughs or runs away, stupid shit...they respect each other but have short tempers...if the 14 year old one would pick on the younger one i reserved the right to pin him down and smack the shit out of him, i made sure they backed each other up before they would beat each other up, i've taught them very well, they've become really tight, they understand the importance of backing each other up if they ever got in a tough spot. i'm 10.5 years older than the middle one so i always had to find a way to have fun with them too so we played a lot of video games and even had nerf wars throughout the house, we had a lot of fun but i made sure that if they fucked up they felt the older brother wrath...one time the middle one tried to steal 50 dollars from me and i knew it was him but he kept 'swearing to God' that he didn't take it and stuff which is kind of a major deal for me...he 'SWORE TO GOD' which means a lot to my family for some reason....and i kept interrogating him and eventually he cracked and i made him hurt for a while after i got the money back but he would never do it again, that's for sure and if he ever disrespected our parents i would also smack him around, i enjoyed the enforcer role, but i wish they were a bit older so i could do it without having to restrain myself so much, can you imagine smacking a 14 year old when you're 24? i was afraid i'd like break his neck or some shit...
