Last December, a grandmother was giving directions to her grown grandson who was coming to visit with his wife. "You come to the front door of the apartment complex. I am in apartment 14T."
She continued, "There is a big panel at the door. With your elbow push button 14T. I will buzz you in. Come inside, the elevator is on the right. Get in,and with your elbow hit 14. When you get out I am on the left. With your elbow, hit my doorbell."
"Grandma, that sounds easy," replied the grandson, "but why am I hitting all these buttons with my elbow"?
To which she answered, "You're coming empty handed?"
