Here is how you know you are tired:
Your husband says, “You know, Kung-Fu Panda was based on a real story.”
Then you say, “Really? I didn’t know that.”
Then he says, “Yeah, you never heard the classic underdog story about the fighting Panda with a duck for a father?”
And only then do you realize that he was joking.
LOL! I’m on the verge of delirium myself at the moment.
