I had this happen to me at the club once. A guy obviously read my body language for something I was about to do, and earnestly told his friend that he was psychic while trying to predict me. I played along, pretending I couldn’t hear him, and I couldn’t stop laughing internally when he got excited saying, “Told you so! I have the gift.” It was fun playing up his little fantasy like a reverse magic trick where the one being fooled is the magician. My only regret was not shattering his shit-eating grin after having confirmed his superpowers, but I rest easy thinking one day it’s going to backfire on him.
