I don't know how universal a thing this was, but when I was in school, they sometimes made us run a mile and time it.
How seriously it was taken, ah, varied. A bit.
Diane and Nanase
When I first introduced Diane, I hadn't planned on her having genuine, real fondness for Nanase. By 2007, however, I did, and everything written since that point has been written with Diane having a crush on Nanase in mind.
Not necessarily a romantic or lustful crush, mind. I was open to the possibility of it being purely platonic. As of a discussion with Susan, however, it's strongly suggested it isn't.
Diane has not, however, expressed any interest in any other women at any point in the history of the comic.
School Logos
I generally associate school initials with gym clothes, or at least something identifying the school, and I actually did start putting the school initials on their shirts. I wasn't sure if it was a good idea or not, because that much text outside of dialogue balloons can be distracting and busy looking, but I figured I'd at least try to have it.
Then I got halfway through and realized I had used for Moperville North instead of Moperville South, and decided that, yes, that much text would be far too distracting.
