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, that sounds easy, but why am I hitting all these buttons with my elbow?”
“You're coming empty handed?”
