OK, but why not let it all out, clear the air a little. Why stop at eight things, and why limit ourselves to things we don't want to tell you about us? I can think of many things many of us at the airlines have wanted to tell you, about you.
Or for that matter, let's talk about those things you're not telling us about yourself:
"I'm booking one seat, but really need a second one for my (slang for derriere). That's OK, I'll make it up by putting seatbelt extenders end-to-end later. I'm sure there will be an empty seat next to me. There always seems to end up being an empty seat next to me"
"I think personal hygiene is overrated."
"I just came back from Africa, where I met this really cool monkey. Can I borrow your hankie?"
"I enjoy airline oxygen best. It's not just pure, but it's also free. You just have to wait until you're on the tracks to ask for it".
"I plan on putting my anti-depressant in my checked bag, and I plan on discovering it in cruise".
"I will trash your lavatory like a rock star at the Ritz".
Etc.
