Grandmother Humor

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. 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 mean you're coming empty handed?"
