I think most people come equipped with a sarcasm detector. Mine, apparently, is defective. I'm terribly naive... I tend to believe what is said to me. Accept now, analyze later.
My husband makes a game of it. Sometimes, he'll throw out the wildest statements, just to see how many seconds it takes before I realize it isn't true. Earlier this week, I caught the end of a conversation he was having with a customer, who was excitedly pantomiming something large that nearly destroyed his home, only to jump over it and hit another person's house. When I asked later what the man was talking about, this was Kris's reply. "Lizards."
