When hamsters cry

I explain to Lucy why a monster had eaten a boy.

Me: He was sleeping in the day.
Lucy: What day?
Me: In the daytime.
Lucy: You mean when hamsters cry?
Me: The day is when hamsters cry?
Lucy: Yes.
Me: What is the night?
Lucy : Thursday.

None of this made sense to me until we were playing later, and one of her dolls did a "Cock-a-doodle-do!"

Me: Was that you?
Lucy: No. I'm not a hamster.

I'm still not sure about Thursday.
