It is pretty hard to exist alongside someone, if that person doesn't at least understand how important flying is to you. Even when they do, it can be tough when the job requires you to be gone so much of the time.
And, help me out on this if I am wrong, I think there are some people who simply do NOT understand why we love to fly, and it's really not worth trying to explain such an important, yet difficult to pin down, subject to someone who just isn't going to "get it". I know a few people to whom I just don't mention flying -- it works out easier that way, and is much less frustrating, overall.
Am I the only one who has difficulty in this area? Just curious!
