GIRL: Come straight down the main road and stop at the flats on your left side. At the first floor, there is an elevator, get in and press button 8 with your elbow.
When you arrive at room 8, press the bell (button) with your elbow and I will come and open.
BOYFRIEND: Ok. But why do I have to press the buttons with my elbow?
GIRLFRIEND: Are you coming empty handed?
