Working the night shift can be rough. A woman working for the postal service catches a co-worker nearly sleep-walking while pushing around a cart of mail and decides to give him a bit of a wakeup call.
She walks up from behind him, then alongside him where you can see that his eyes are basically closed.
She doesn't make a noise at all, instead waiting until he realizes she snuck up besides him.
Dude nearly jumps out of his pants when he realizes she's unexpectedly crept up on him!
