If I'm reading Classics, it's to revisit (or, more likely, actually read) something I was supposed to have read in high school or at uni but blew off (& survived the class anyway) because teenagers are real know-it-all jerks sometimes.

I will occasionally do a "Classics Catch-Up" choice, but I'm more likely to read something escapist or "easy" when I have very little time to myself. That meant a lot of YA and graphic novels at one point; more recently, it means romance & erotica. Between the YA/graphic novels phase and now, I was really into nonfic.

If I get into a slump, I read short story anthologies and essay collections.
