Stupid is as stupid does

Today, I was waiting for the lift at my apartment block when this youngish lady in her twenties also came to wait. I  know her to be one of my neighbours somewhere up on the higher floors.

She was on the phone yakking away with her friend while tossing & juggling her house keys with the other hand. I don't like to stereotype people but this slovenly dressed ah lian gave you the feeling she was a walking disaster.

True enough, when the lift doors opened, she fumbled her keys and it dropped right into the crack between the landing and the lift floor.

"Dammit, shit!" she screamed into her phone to her friend, "this is the 3rd time my keys got into the gap!"
"Damned idiots, why did they have to make the gap so big?!!"


Duh?
