Heinkel: Get some sleep, Timothy.
Timothy: But it’s still light out!
Heinkel: That’s because we’re flying towards the sun. You need sleep if you don’t want to be very jet-lagged.
Timothy: But I can’t help it. I’m so excited!
Heinkel: Here’s an Italian-Japanese phrasebook. Memorize it.
Timothy: All of it? Do you really think I can?
Heinkel: No, I think it’ll keep you from bothering me.
