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