Conversation with my little brother, who's 8 years younger:
Me: What time are you waking up tomorrow?
Him: Early. About 6? 7?
Me: Can wake me up? I need to do work.
Him: I'm sure.
Me: No, really. I really need to do work.
Him: But you'll just say mmm and go back to sleep and wake up at 10 and stone for a bit and have lunch and...I dunno, spend time somehow, and then when I come back at night you'll say you haven't done any work yet.
Me: (Indignant silence.)
