Hmmm, I just tell them I'm a pilot (if asked). It looks a lot better than telling them something else, then later in the night they find out what you really do. Then you just look like some jerk who thinks his job's sooo F-ing cool that you can't say it out loud.
Sure, some think it's just a line, so what?
P.S. I used to think my job was sooo F-ing cool that I really couldn't say it out loud. I was so proud of what I'd achieved against the odds and how well everything had gone, that I'd break into a huge grin if I ever said "I'm a pilot". Not because I thought I was cool or anything, just because I'd always wanted to do it, from the moment of conception, and I'd managed it, and it hadn't quite sunk in yet.
