i get pissed (even if it's not my weed) when someone will sit there and hold the joint/sweet til it's like half gone and they're the only one that's hit it... i will however keep my mouth shut (not even hint they shoudl pass it, cuz it's their weed, technically they can smoke the whole thing without passing if they want to, but i consider it really fucking rude) if it's their weed... i'm still pretty laid back even if it's mine, but if you been holding it too long i WILL Say something to you if it's my shit...
