It's Official

 Conversation with husband: "I need to get your lunch packed."

Reply: "I'm not going to work tomorrow." 

Me: "You're not?!!!"

Him: "Nope."

Me: "Why?" 

Him: "Because it's Friday." 

Me: "Right....but, why aren't you going to work?" 

Him: "Because it's Friday." 

Me: "What's going on though?"

Him: (very patiently) "Today is Friday and I don't work tomorrow."

Me: (dumbfounded) " No...today is Thursday...."

Him: "It better be Friday because I'm not going to work tomorrow."

And turns out that he's right.
