what do you like to do for fun?

Asking someone "What do you like to do for fun?" is a fairly common question. But to be perfectly honest, it's a question that used to terrify me. What do I say? What's the right answer? I don't do anything that's cool. What hobbies do I have? 

Paralyzed by the fear of being judged I didn't know how to answer. I felt trapped in a corner unable to breath every time the question was posed to me. My perfectionist tendencies made me think that I had to "be good" at fun. Whatever the hell I thought that meant.
