the only time some kid tried to rip me off was when i was a newby and i didnt know what a full 8th looked like. Thankfully one of my friends explained to me what it should look like and i said to him when i got it "what the fuck is this?" and the guy i got it from looks at it all innocent, "o shit i didnt even look at it, i'll smoke u up the next time i see you" But, that was the only time, i usually go through kids i know and im friends with. Besides im a pretty big kid so many kids dont want to try to totally fuck me over. and im not trying to act tough or anything, its just that i got some size on most of the kids in school, thats all.
