How to take a compliment.

While discussing the issue of how to graciously receive a compliment, it was interesting to hear the varied points of view from the group in the social network where the discussion was taking place. The issue was discussed as asking how best to respond to someone (specifically in the workplace) giving you a compliment and whether or not to direct a compliment right back to them or to graciously accept their compliment and say a simple "Thank you.". What do you think about this topic? Do you feel that you should just give a sincere "Thank you." response, or do you think that their compliment leaves you with the obligation of returning the compliment?
