Bus! Stop!

"Bus! Stop!" a boy yells, as his bus pulls away one early morning. He must wait for the next bus. But the next one does NOT look like his bus at all. And neither does the next one, or the next. At first, the boy is annoyed. Then he is puzzled. Then intrigued. The other buses look much more interesting than his bus. Maybe he should try a different bus after all, and he's glad he does!
