My parents didn't smoke and, to be honest, it never occurred to me to smoke either. DH was the same - his argument was why would you want to burn money? I think my grandfather smoked, but am not sure and none of my friends smoked. Fortunately neither of my children do - although DS did admit once that he had tried a cigarette, but (bless him), stopped because he thought I wouldn't like it.
My SiL did smoke when my DD met him at university (he was also a vegetarian), but she stopped all that after a couple of years. None of our friends have smoked for donkey's years.
Feeling like im on the slippery slope!!!
British style conquers on this occasion.
for your efforts.
and became more considerate to non smokers.
