Quoted because this is one of the situations under which I draw best.

Also:

I draw best when I'm venting out a lot of sadness or rage, when I've just read something that inspired me (original fiction or fanfiction), or if I'm very passionate about the subject matter (some of my best works are...actually fan art.)

when im not sopposed to draw, like at school or late at night -.-"

I get the best ideas in class :P I don't like drawing characters around people for whatever reason, so I go for abstract or funny, surreal stuff. I have lots of scrap paper from 11th grade math and history classes that I'm going to use and redo....sometime.

I also draw well when I'm travelling, listening to music, or really upset/angry about something, and usually very late at night 0:

I draw best when there's not a lot of sound in the room, and usually in the evening or late at night.

Oh, I also draw well in school, if no one is watching me.
