Today we were driving home from school and Alex says, "I'm just feeling a little glum about something." Then he told me about a kid in his class who fell off one of the tricycles and hurt his knee. He also refers to the kids in his class as his "schoolmates". If he's trying to convince Benjamin to do something his way, he'll say, "Suppose we do this . . ".
I get a kick out of his kind of old-fashioned vocabulary and I wonder if it comes from letting him watch too many Thomas the Tank Engine shows.
