A grandmother is giving directions to her adult grandson who is coming to visit.
“You come to the front door of the apartment. I am in apartment 301. There is a big panel at the front door. With your elbow, push button 301. I will buzz you in. Come inside, the elevator is on the right. Get in, and with your elbow, push 3. When you get out, I’m on the left. With your elbow, hit my doorbell.”
“Grandma, that sounds easy, but why am I hitting all of these buttons with my elbow?” he asks.
“What… you’re coming empty handed?” she exclaims.
