Heh...I had one of those type men sitting beside me on the subway in DC. Asking all kinds of personal questions, which my mom happily answered for me including my last name which she very thoughtfully spelled out for the fellow.
Ew! You'd think your mother wouldn't be so naive...
Luckily in my case they generally just wanna spill their guts...but I've gotten a few weird questions, too.
I don't like flying alone!
