watch your ass at school. i hope its not during school hours thatd just be dumb. cant you meet him at a park or go to his place? there isnt really a way to avoid it, everyone gets ripped off every once in awhile if your dealing with shady dealer. you could bring your friends and i agree thats good it sounds smart but 1, if theres one of him and you and your friends there at school...too many people for one deal. a good dealer will always weigh in front of you, if your at your/his place. you really just have to learn to eyeball this and that and now your weed!
