On the one hand, girls and women smoke for weight control and the foul spawn of satan are marketing candy flavored tobacco.
On the other hand, our 7 yo asks "Mommy, what is smoking" when reading a children's story from the 1960s. That's when we realize that nobody smokes in our neighborhood. Nobody. Our children don't see people inhaling burning materials.
Tonight my date* and I had a beer at a local bar -- which has been smoke free for a few months - along with the rest of the metro area. It was very pleasant.
When I was 7 I definitely knew what smoking was, and I knew about cleaning ashtrays. It's easy to miss progress.
