I had a friend once rip me off, she sold me about .4-.5g and told me it was a gram. I trusted her because well she was my friend and payed her the $15. The next day I asked for my money back and I'd give her back the bag cause I haven't smoked any yet cause it was skimpy. She said no, go figure huh? Funny part his a couple days later she calls me looking for a gram, so I sold her shit back to her and she didn't even notice. What a bitch, huh? Those are the people I really try to steer clear of. It's too bad you do see a lot of them in highschool.
