It was lucky he hadn't finished his sentence. He had to get out of the habit of speaking pointless words.
He didn't know yet that everything he saw had its importance, and became a little more important with each day. You think "school." And you have a ready-made image of it in your mind. But in some cases, the tiniest detail might one day become so precious that you would never forgive yourself for not having looked at it more carefully.
