My daughter and girlfriend are the only ones who KNOW what I'm doing. I mean it's hard to hide when we are all under the same roof. Actually when I found out she had experimented with weed was when I decided to have the talk with her about bringing my grows indoors. Basicly I told her if you don't want our house busted into, by either thieves or cops, and you don't want to see your dad in prison (because I'd go one way or the other, either by the law, or for shooting a thief) then you don't tell anyone! She is a level headed kid, good student, polite etc. She could care less about the grow, untill they are hanging...lol. When we talked I let her know that she had been around it her whole life, and relayed a couple cute stories to her. One I'll share with you all.
She was about 4 and I had picked a few nugs and set them on the window sill to dry out, she had been out to my patch with me and watched me look over the plants, pick etc. So I set them up on the window and say to her, "Now don't you touch that, thats daddy's smoke." Like 3 weeks later my then mother -in-law was over and my daughter goes to a big potted house plant we had in our living room, and starts picking leaves off of it, and setting them on the window sill, she looks and points her finger at her grandma, and says "Now you don't touch that grandma, thats my smoke!" My wife at the time did not see the humor in it, but it's makeing me laugh right now remembering it.
I still have not smoked with her, even though I know she has been in my mason jars. She has asked me to, for some reason I don't feel comfy with smoking with a 16 yr old, and I don't want her to think she can just burn in front of me. I am supposed to be the authority here. I have told her, that I don't want to know. Act like you don't have a "cool" dad, and hide it like the rest of your friends have to. I'm sure we will burn together someday, but I'm thinking more when she is an adult 18 or so. Although she is definately more of an adult than I was at her age. Honestly I would rather her smoke weed than ride around drinking, which seems to be socially acceptable for kids her age. I'm a drunk, who doesn't drink, but she saw plenty of stupidity growing up (I'm not proud of that, but thats the way it was) so I think she knows first hand the evils of alcohol, at least in our irish blood, geneticaly we are screwed when it comes to drinking. I know I was blazing at that age, more than I do now.
I'd say this could be a bonding experience for the 2 of you...Good Luck with whatever you decide!
