jus sayin ur guna pop out to see a mate or summit, take a can of deoderant go around the corner for a cheeky smoke, the perfect crime, jus dont get caught! or jus wait till ur parents go to sleep then toke wen ever wherever by the morning the smell has faded.also another trick to keep smoke contained in one room is to put a pillow over the crack under the door. it works great, or have a joint then light up sum josstix incense thingys and blame the smell on that. thats what i used to do, until i got caught now my folks dont mind me smokin it so its all cool.
