An elderly grandmother was giving her grandson directions to her apartment.
Grandma: “I am in apartment 4012. There is a big panel at the front door.
With your elbow, push button 4012. I will buzz you in.
Come inside, the elevator is on the right. Get in, and with your elbow, push 4.
When you get out, I’m on the left. With your elbow, hit my doorbell.”
Grandson: “Grandma, that sounds easy. But, why am I hitting all these buttons
with my elbow?
Grandma: “What……You coming empty handed?”
