Time QOTD

A conversation like this happens multiple times a day.  She's clearly trying actively to figure out the concept of time.

During bath time tonight.

Me: Okay Callie, in 2 minutes we're going to wash your hair.
Callie: What number is it?
Me: You mean, what time is it?
Callie: Yeah, what time is it?
Me: 5:03.
Callie: What time is washing my hair?
Me: 5:05.
Callie: (pausing a second) Is it 5:05 yet?
Me: Nope.
Callie: (pausing a second) Is it 5:05 yet?
Me: Nope.
Callie: (pausing three seconds) Is it 5:05 yet?

And so on...
