어떻게?

How does anyone feel when they receive compliments? I mean I definitely feel flattered and secretly happy inside. But how should I react to it? Smile and thank them for it? Or ignore them and feign ignorance? Something to think about since I rarely receive compliments and I really don't know how to react to them. I guess I'll just end up secretly happy and then look awkward. It's a good thing not all of them are told to me face to face.
