Typical dialogue with people who don’t know me very well if I stay at their place or similar.
Them: Don’t you ever sleep?
Me: I was asleep right before you started talking to me.
Them: But you answered right away! That’s not asleep!
Me: That is how I sleep. I was fully asleep and I woke up the moment you started talking.
Them: But that means you weren’t asleep!
Me: Yes, I was fully asleep, as deep as I ever sleep.
Them: But you heard everything I said!
