@pleonasm - She probably couldn't smell how overpowering it was. I used to smoke and it's amazing how much difference it makes to your sense of smell.
I don't know how my friends put up with it now. I hate the smell of old cigarette smoke with a passion. And that bad breath smell of someone who is a chronic smoker is even worse. Although you can usually prevent that by scrubbing your tongue with the toothbrush when you're brushing your teeth.
