^Man no offense and I don't know your family but thats the problem a lot of people make for themselves. They think that it just can't be done, at all. So they don't get creative when thinking of ways it could work. I've smoked up in the same house on the same floor as my aunt and uncle, their two dogs, my mom and dad, and my three little cousins that wonder around the house, and I had to leave the door open in the room I was in. You just gotta get creative and plan it out step by step.
