Chester's been having some trouble with school this year. We're not entirely sure whether he's missing his friend (in a different class for the first time in three years) or having trouble with the way the teacher is teaching (Klaus had her for 5th grade, too, so we know it's not the teacher) or some other reason (or some combination). He's been feeling frustrated and saying he doesn't want to go to school, which is completely out of character for him. :(
So I was asking him a little about what he thought the problem was--lessons too fast (teacher not explaining enough or not visual enough) or too slow (busywork). "I found out recently that doctors and other earners-of-graduate-degrees have an average IQ of 125, which is the same as you, so I know the problem isn't that you're stupid." I told him, and we talked about the difference between how much you're capable of learning (IQ) versus how much you know (5th grade). He perked up considerably after that, so apparently he was thinking he was stupid. He's very very hard on himself.
The next day we were at the school dessert social, on the swings, when I made some general comment about brains and school. Chester says, "Yeah, I'm smart enough to be an average doctor!"
