The bus is late, thought Blurtso. Or I’m early. I guess I’m off schedule. I didn’t plan on that. I wonder what I should do while I wait? I could just stand here, or I could do something. I could take out my books and review for tomorrow. I wonder how much time I have? If I have a long time, I’ll take out my books. If I don’t, I’ll do something else. Like what? I can enjoy almost anything for a short time. But a short time can become a long time if you don’t know how much time. I should find something I enjoy for a short time, and for a long time. Like what? It’s not easy when you get off schedule, and you have to stop and think.
