Interesting thought and one I may have to be concerned with down the road.
Fortunately for me, my daughter is ridiculously picky when it comes to what crosses her palette. This would mean to me that beer and cigarettes are pretty much out of the question unless they can make them taste like Mac and Cheese or strawberry milk.
(Or at least I hope)
Neither me or my wife drink alcohol and I smoke on occasion (which repulses her). Any other 'not appropriate for all eyes' activities are done behind closed doors/after hours.
