well my parents smoke but we keep it sepreate from one another. yeah they know i do to. so yesterday my dad randomly comes up to me and say "you got any papers?" i was like "yeah why u need some?". and he said yeah. so i grab some papers and give them to him. then about 5 mins later he yeslls again, "you got any more?" so i went to my room and got him 2 more. well then him and his girlfriend both look at me and say "you dont know where you got this." and she hands me a joint. haha i couldnt bealive it! then i went to my friends grad party and got mad baked before. good shit too. but we still wont like smoke with each other... too awkward.
I had to put a note in my stash when my girls were growing up. I found out they were taking my weed. The note said that they would have to smoke with me if they wanted to smoke my weed. Took them a year to get the nerve to ask me about it. We smoke together all the time now.
my dad's gf told me if i ever "needed" any i could ask her anytime. she gets some kinda shitty stuff though. so its polite of her to give it to me and i alwyas say please and thank you no matter how shitty it is. its still a nice gesture.
I'm the same way with my dad. It's just instead of papers, I 'give' him weed. It would be way too awkward to sit down and actually have a session with him though.
