Owen: I can't WAIT for my birthday!
Me: Well, you have a little while to wait, honey, it's not till the end of the summer.
Owen: But I can't wait!
Me: When we're really looking forward to something, time seems to pass slowly, doesn't it?
Owen: I CAN wait till my birthday.
Owen: I'm not looking forward to my birthday anymore.
Me: What do you mean?
Owen: Is time passing faster now?
