I am a part-time closet smoker now myself, just being honest. I don’t think walking past someone smoking a cigarette is going to hurt you. I don’t even think being in a smoking bar for a few hours will do anything to you, but I definitely think being a non smoker living full-time in a house full of smokers has an effect over time. I step outside for my cigs.
Almost ever time I respond to a smoking thread I am sorry that I did (not you). They are convinced that it is all about control. The only thing I want to control is the air I breathe into my lungs. I will avoid smokers ever chance I get, not control them, AVOID them.
