The Care and Feeding of Compliments
Lots of people don't really understand compliments, what to do with them and how to respond to them. Often the response to a compliment is to deny it: "You look great in that dress!" "What, this old thing? It's nothing special." Whether this is some kind of social false modesty, I don't know.
Other people deflect them with jokes: "Your hair looks nice today." "So what was wrong with it yesterday?"
But some people really don't know how to deal with a compliment at all. Say something nice to them and they either look at you blankly or pretend that they haven't heard. They are uncomfortable with compliments and have no clue what to do with them.
Somewhere, long ago I read where someone described a compliment as a gift, and the appropriate response to recieving a gift is to smile and say "thank you".
That works for me.
