Ideas . . . Where Do They Come From?

I had an epiphany last night, and I'm annoyed that I didn't think of it sooner (but you can't really control when you think of an idea-- it took me seven months to realize that I can use the giant pull down movie screen in my classroom to cover a quiz on the board, so then I don't have to photo-copy it or dictate it-- and if I forget to write it on the whiteboard before class, then I can hide behind the screen and write the questions while the students are busy doing something else, which they find very amusing) and so when Alex stumbled in with his blanket at one in the morning and squeezed between Catherine and I, I went into to his room because now he has a full sized bed and I slept there-- but I was so comfortable that I was nervous I wouldn't wake up so I need to put an alarm clock in there for next time.
