My dad took the same stance originally with me. Well he didn't smoke with me but he was very accepting. It was like that until my mother found out, then his stance changed. He of course used to smoke and deal pot when he was younger, my mother used to smoke as well. They changed obviously. I don't bother to call them hypocrites though. I wish you the best of luck with your kids when they get older. This world only seems to get worse.
