A grandmother is giving directions to her grown grandson, who is coming to visit with his wife:
“You come to the front door of the apartment complex. I am in apartment 14T. 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, don’t worry, I know my way, but why am I hitting all these buttons with my elbow?”
“Are you coming empty handed?”
