My son is only 10. The other day I asked him what he wanted to do when he grew up. He said " Well I guess I can't be a professional football or basketball player cause I won't fly - so I don't know." I thought he was going to say because of CF -but he didn't. I told him he has never flown - so how does he know he wouldn't like it. It just breaks my heart - cause he really is good at sports and takes it very serious - and is better (right now) than any non-cfer. But I'm not going to crash his dreams!
