Compliment etiquette

So I don't have an answer to this one.

It's not that serious, but I'm just curious: How do you respond when someone compliments something or someone related to you for something you had nothing to do with, but not you yourself?

What I mean is when someone tells you "Your dog is so cute!" what do you say?

Or, when your girlfriends tell you "Your boyfriend is a real hunk!" what do you say?

I don't know, but I've always felt weird in those situations like I'm accepting unearned praise, you know?

Then again, I'm nuts that way.

I'm thinking about this 'cause my wife and I were out handling business the other afternoon and a woman at this office we visited turns to me and says "She is so pretty!"

Without thinking I replied "Thanks!" Then I thought about it. I agree with that woman, but I didn't have anything to do with it.

How do you guys do it?

The only time I guess wouldn't feel like a dork when getting someone else's compliment is if - when we have kids - they say "What a cute baby!" or "Your child is so smart!"

I won't have a problem saying taking credit for those, 'cause I'll be half responsible for that kid's good looks and big brain.

I know. I'm nuts for even thinking about these things, but I'm still curious.
