I spent part of the morning working on a new short story. Another one from a child's point of view.
I was in this mode, thinking of kids and their views of the world, because I'd done a little reading at JJ's school (we read "A Present for Toot" by Holly Hobbie). Watching JJ and her classmates afterward, I was struck by the extreme polarity of school time. Either the time passes so quickly you don't notice it, or the day never seems to end. A feeling I remembered strongly from my own childhood, too.
The feeling changes quickly but it is always intense. JJ shifts from intense boredom to intense engagement to intense boredom again. But it is intense all day. No wonder JJ is so worn out in the afternoons.
