Both my parents smoked when I was a child and it irritated me so much that at one point I thought I would join them just to stop me hating them. I too am an anti-smoking nazi and take every opportunity to tell my kids about the the perils of smoking. I often point out to them people driving crap cars who smoke and I tell them that if that person did not smoke they could probably afford a better car - my kids get the logic. As for that mother, I think smoking round your kids is an abuse issue and I would like to see people like her prosecuted.
