I do think maybe some folks are looking at you as if you are a something of a symbol of their own daughter or son (and by extension, their own selves); so just to play along here, if my beloved daughter or son or niece or nephew expressed themselves to me the way you just have, and had the history that you say you have -- I'd say, simply, "Do what you think is right".
I can totally see that and I do readily understand that perception. As concerned parents it is easier to feel weird and even oogy about our youngsters getting into this thing. However, I would highly highly encourage every smoking parent to have a little talk about this device with their child. This is because of the fact that they (smoking parent) already have a smoking history so in a childs mind they already have some small unspoken permission to try either smoker OR vaping.
I have a lot of experience teaching children and I have noticed first hand how often we as adults talk the talk but dont always walk the walk. We tell them to be quiet at the movies but then whisper with our spouse seconds later its totally confusing! Young kids dont know the difference and teenagers wont care to analyze the difference when their mom or dad tries to take a moral standpoint. A teenager or young adult will just want to make their OWN choice and practice their adultness and whether that is influenced by social information, moral information, or factual information will follow AFTER that desire to express their own autonomy.
Better to give them factual information and ANSWER their questions. They will want to know exactly why its okay and makes sense for you as an adult (which is what theyll become someday soon whether you like it or not) to do this thing all the time. If you want to steer them away tell them about the nitty gritty even though vaping is healthier you still have to buy all the stuff, maintenance, get new parts etc. etc. Maybe theres another hobby you can steer them towards instead but only after youve shown them what is really involved with this one.
Holy crap
