Little Brother asked me if I had a couple of large cardboard boxes that he could take to school. His class is working on a skit and they need the boxes for props. Or costumes. I'm not sure which.
I found a couple of boxes for him, and I told him that when I go to library today, I'd bring the boxes with me and drop them off in the hallway near his classroom door.
"Just bring them in," he told me.
"No, I'll leave them by the door. I don't want to interrupt your teacher."
We went around and around like that for a while and then he thought about what time I'd be arriving at school, and realized that he won't even be in the classroom at that point--he'll be in Spanish.
"So my teacher won't be busy! You can knock on the door and bring the boxes in."
"What if she's not there? What if she went down to the office?"
"Well, then, you can wait."
(Or I can leave the boxes in the hallway, like I originally planned to do.)
