Step 1): Smile
Step 2): Say "Thank you!"
That is one way to graciously accept a compliment. So if you get a compliment, try accepting it in two easy steps!
A Simple Thing:
And if that's not enough for you, here's the guilt trip - in a metaphorical sense, a compliment is like a gift. By refuting it, it's the same as giving a gift back, which is rude (and crazy).
In a literal sense, if you deny the compliment, it's kind of like saying the person who gave you the compliment is lying.
Plus, the compliment was probably true. So just take it and bask in your awesomeness!
