The keys for the what?

This morning Nichelle was extremely kind, and took Isaac to school so I could sleep about another hour—trust me, I needed to.

Anyway, around 8:00 am, David knocked on the door, and I told him to come in. He had a set of keys from some toy handcuffs that had come with a police role-playing kit he’d been given. Now, understand that David is quite advanced in his speech for his age, so I was ROTFL when he said, he had the keys, but couldn’t find the cheese puffs they went to.
