Was that a compliment!

A recent conversation with a rather young (22), female employee who works for me...

Me: ...and at 57, I still feel much younger than that.
She: Wow! You're 57?
Me: Ah huh
She: I wouldn't have guessed you were that old.
Me: Really? How old do I appear to be?
She: Not more than 54 or 55!

True story.
