I had a college friend who was looking for someone for a date. I had known a guy friend who was also looking and so i and another friend arranged a date for them to meet. This lady friend asked me if the guy does or doesn't like a girl that smokes. When i learned that he prefers a girl that doesn't smoke and so i told the girl.

When the date came they were introduced to one another. I was surprised to see the girl lit a cigarette after the meal. So that was a hint that she doesn't fancy the guy.
