The following conversation took place with one of my students who is disturbingly smart, but occasionally lacks a bit in the common sense department. (Note: I'm the same way, only she's smarter than I've ever been.)
Student: The music's hard to read.
Fiddler: Yes, I think there's a reason for that.
S: I don't know what that reason is.
F: Well...think about it.
S: Hm...the music's kind of curved, so it's at a weird angle.
F: True, but that's not the current problem.
S: I don't know.
F: What are some reasons that people sometimes can't see things?
S: Sometimes things are too far away, but I'm really close to the music.
F: Right. What else?
S: Some people have poor eyesight, but my vision is perfect, so it's not that.
F: Also right. What else?
S: *ponders extensively* I just don't know.
F: What time of day is it?
S: OH! It's DARK in here! Maybe I should turn on the light!
F: Maybe you should.
*cue blinking as eyes try to adjust to sudden flood of light*
