Compliments are just that: a compliment. Personally, I really enjoy when someone says something nice to me. I put time and effort into my character's physical appearance and glamours, so it's nice when someone recognizes you for it. I shudder to think how some people would react if someone in life away from the game said, "Hey, you look nice today!"

Here's a helpful tip: you say, "Thank you!" or "That's really nice of you, thanks!" and move on. Why must everyone always read into everything?
