Never, ever, correct a woman that tells you about an airplane she saw. Say "wow, thanks" and realize that she probably doesn't know. Accept the fact that she is trying to express an interest in your passion. More than once in my life I've had a girfriend tell me about a really strange airplane she saw landing. When we get to the airport it turns out to be the same B-17 (or whatever) I see 5 or 6 times a year. They always know I've seen it before, but they still appreciate the Thank You. It's a two way gift.
The day you stop learning is the day you should die.
