Okay, I'm not sure if this will work, but let's try it. 1) Act like you're reading something personal I wrote in your card. 2) After a couple of seconds, laugh as though I wrote something very funny, in fact, tilt your head back when you laugh so it looks extremely funny. 3) Now nod your head as though I wrote something very serious an heartfelt. Maybe touch your heart and exhale, but don't make it look forced. 4) Okay, now close the card, look at me and mouth the words "thank you".
