Fiction: Stories about imaginary events and/or people.
Non-Fiction: An account, narrative, or representation of a subject which an author presents as fact.
And do tell me what types of either that you prefer. I'm not even gonna put in the "I don't read" option because everybody has enjoyed a novel or prose or poetry at some point in time.
I'm really a fiction type of person. I typically lean toward Science-Fiction but sometimes I'll read a Fantasy novel. Historical Fiction is nice every once in a while, too.
If I do feel in the mood to read non-fiction I tend to read Biographies.
