"Are you bored? Do you need more of a challenge?"
"It's fine, sir." Unless you want to assign me some large-prime factoring problems.
"Right, then. Don't hesitate to call on me if things are moving too slowly or too quickly. I mean that."
I snuck another look at him. He seemed sincere.
"Why aren't you playing with your chums?"
"I don't feel like it."
"You just wanted to think?"
"I guess so." Why wouldn't he just leave me alone?
"It's hard to come home, isn't it?"
I stared at my shoes. What did he know about it?
