One night I was smoking a bowl while my friend was over sleeping. And my dad(who tends to not sleep some nights) walked in to see if I was awake and Ithink he asked me if I wanted food or something...anyways he opens the door and I am hitting the bong and then he looks at me and closes the door. lol. I just started laughing. The next morning he didn't really mention it either. Anyways jus thought i'd share my only walked-in-on experiences.
