Subject: Visiting a Jewish Grandma!!

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"?
