I heard this last week on Discovery Wings and it is sooooo true.
"Don't ever ask a pilot if he is a fighter pilot. If he is he will have already told you and if he isn't you'll hurt his feelings".
A conversation I had about a week ago in FCharleston. My son was looking for an SF Flag.
Vendor: Were you in Special Forces?
Me: Yep.
Vendor: Were you one of those Green Berets?
Me: I wore one.
Vendor: Were you one of those "Elite" Forces. They're tougher than the Green Berets. They go behind enemy lines for six months at a time.
Me: WOW!!
