Me: Why's you're pillow on my side of the bed? Get it over your own side!
Kelly: It's not my fault. It's a pillow monster coming to get you!
Me: Don't be daft! Pillow monsters don't eat people!
Kelly: They don't?
Me: Of course not!
Kelly: Then what do they eat?
Me: Teddy bears.
Kelly: Right, OK...
Me: Yep... That's why our pillows are getting kinda flat.
Kelly: What do you mean?
Me: Well, my teddies are too high up for them to eat them... Pillows can't climb, you know.
Kelly: Of course... Whatever you say.
Me: But I know they eat teddy bears.
Kelly: You do?
Me: Yep.. If you think about it it's obvious... They're both filled with almost the same stuff.
Kelly: OK... Whatever you say... I think you should go to sleep now though.
(In other words, this conversation is getting too weird, even compared to some of our others).
