Why should I be the one who has to walk away? Why are the people NOT smoking the ones who have to be bothered and walk away? That makes no sense. The smokers are the ones changing the smell of the immediate vicinity. Why do the people who AREN'T changing it, but rather enjoying clean air, be the ones who have to walk away?
Sure, let me walk right up beside you while you are, say, watching the tigers at the zoo with your children. I light a small fire that gives off horrible smelling smoke, a smell that gets in your hair and on your clothes, and you are breathing in when you DON'T want to. At this point, I simply tell you that if you don't like it, walk away.
That is utterly ridiculous.
I don't care if second hand smoke has ZERO health risk. I shouldn't be forced to smell it, nor should I be forced to walk away.
