My mom and dad both smoked growing up, only me and my siblings had no idea my mother smoked. My father did it openly, my mother would go upstairs to the bathroom and be in there for awhile chain smoking. None of us ever realized.
Skip to several years later...we (the 4 of us) still have no idea my mother has been smoking our whole lives. My sister "S" started smoking when she was 11. My sister "R" started smoking at 15, and my brother "S" started smoking when he was around 15 too. I started at 20 (long story). Once we were in our late teens and early twenties, my mom revealed to us that she smoked all those years in secret because she didn't want us picking up the habit. Dad died when we were young (not smoking related), so she figured that since we didn't see anyone smoking, we wouldn't pick up the habit.
It was a little funny, since my siblings all hid their smoking from my mom for a few years, and my mom was hiding her smoking from them at the same time. At one point, my mom knew my brother was smoking, and he knew she was, but they would not let the other one see them smoking and both kept pretending they didn't smoke.
I don't know what any of this means in regards to how a child perceives the smoking and what they do with that knowledge. For me, I didn't think anything of my dad smoking. It was just something he did. My mom not smoking didn't make me want to not smoke. It was just something she didn't do (or at least I thought she didn't).
The PV will be good for me in so many ways, but the biggest one for me is that I won't be affecting my daughter's health. I'm the smoker that gets crap from other smokers because I smoke inside my house and my car. I feel guilty about it, hence trying to quit a million times a million different ways. My doctor told me that the second-hand smoke is reduced by going outside, but that it still clings to your hair, skin, clothes, etc.
