i'm 15 and i got an 13 year old bro. he will do ne thing to get attention. he talked to me a couple times about pot. he doesn't know i smoke but i think he kinda does, if that makes any sense cause i'm stoned right now. lol. but yeah i told him that i dont care if he smokes weed but i told him that he would get caught (which he would cause gets caught everytime he tries to do sumthing "bad"). i've told him a couple times not to do it but thats only because i'de feel like i fucked up in life if he like gets arrested in the future. so ur bro doesn't wanna feel like he fucekd up and was a bad big brother. u gotta understand that. he probly knows that weed isn't sum big time hard addicting drug he just would have a guilty concious if he just sat there and let u do it. just like i dont care if my little bro smokes but i wouldn't just go up and hot a bong with him
