GIRLFRIEND GIVING HOUSE DIRECTIONS TO HER BOYFRIEND

"Come to the front gate of my apartment where u dropped me,
Look for flat 9A
U'll find a lift on ur right
Then hit 9 with ur ELBOW.......
And get out of the lift u'll find my flat on the left
Hit the doorbell with ur ELBOW & I'll get to open the door for u"
BOYFRIEND: dear that seems easy but why am i hitting buttons with my ELBOWS only
GIRLFRIEND: "OMG!!! Are u coming empty handed
BOYFRIEND: (speechless)
