Becky's grandson and his wife are coming to visit her for the first
time. So she is giving him the directions to her flat.
"You come to the front door of the Golders Green block of flats. I am
in flat number 32 on the 14th floor. At the front door, you'll see a
big panel of buttons. With your elbow push button 32. I will buzz you
in. Come inside, the lift 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"?
