What is time....really?

Jack is at the stage where he knows just enough about numbers and letters to almost tell time or spell something, but not quite. For example:

Jack: When are we going to the beach?
Angie: In about two weeks.
Jack: Two days?
Angie: Two weeks.
Jack: Two minutes?
Angie: No...two weeks, that's 14 days.
Jack: Two pounds?
Angie: AHHH! You have to sleep at least 14 times before we go.

So, you see, we go through this several times a day. I think he really tries to understand and throw words out there that he knows, like minutes, pounds, o'clock, and so on. So then, last night, I was trying to decide if I should put him to bed before Jon got home from his meeting. I asked him...

Angie: Jack, can you see what time it is? (Just knowing I was asking for it.)
He simply answered...
Jack: Well, it's 7, E, H.
Angie: Okay, that's 7:34.
That one brought a smile to my face. :)
