I started out just nodding to them. That seemed most appropriate, what with the earliness and the hotness and the lateness to school. Then, about two weeks ago, I introduced the, "Hi!" and worked my way up to a quick, somewhat hesitant, forced cheerful because, remember, it's early, but still quite friendly "Good morning!" along with the nod. I felt pretty good about it.
This morning, the one in the wagon looked up at me through a curtain of yellow hair, and said (with awe? anger?), "You sound just like Mickey Mouse."
And you know what? I COMPLETELY DO!
