Me, at 16, about sophomore in Highschool: "Mom, I'm buying a hookah" (off hand at dinner)
Mother: "OK, do you have enough money?"
" (flabbergasted at her response)
Mother: "Pick a pretty one"
Me: "Uhh, OK!"
That's what got me started, her roommate apparently had one in college, she saw it as a great social interaction item, and she loved my friends, so I guess it all fell into place.. Huh..
I asked her why she was so lenient later on in my life, and as long as I wasn't getting drunk or doing other things illegal she could not care.
