But David wasn't talking to his cat, and he wasn't talking to himself.
He was talking to the pretend child who was his playmate and who had come there holding to the other handle of his cart and helping him drag it.
And he was so busy that he didn't notice the great wagon that was just about to turn the corner.
The driver called to him.
"Hey, little boy! Don't get run over."
David scrambled up on the sidewalk before he even looked, for he remembered to be careful.
Then he looked, and he saw a big wagon that was drawn by two horses, and the wagon was loaded with short, shiny boards, tied together in bundles, and on top of the bundles of short, shiny boards were bundles of shingles, a great many of them.
David knew what shingles looked like when they came in bundles, but he wondered what the shiny, short boards were.
But he didn't ask, because the horses were almost trotting, they were walking so fast, and the driver seemed to be pretty busy.
He supposed that the shingles and things were going to the new house, and he watched the wagon until it stopped there.
