I was at the entrance of the high-rise apartments and I phoned my grandma upstairs and she offered me her instructions: “Well, Josie…I’m at 354 you got to hit the green, square button with your elbow at the entrance where you are; and I’ll release open the glass doors and then go to the lift on the right and punch the button with your elbow and then get in and punch 3 with your elbow and then when you are up on 3 look for Unit 54 and punch on its button with your elbow and I’ll open the door”
“OK, easy, grandma… But why am I punching all these buttons with my elbow?”
“What?” my grandma screamed. *“You mean you are coming empty-handed?”
