The One About The Elevator

I was just thinking today...

A person gets into the elevator and presses the destination floor.

Elevator dings. Doors open. The person walks out while another walks in.

The person glances up and realizes that it was the wrong floor - got off the elevator too soon! Walks up one floor.

Come to think of it, the person was... me. >.<" (This happened some time ago already... suddenly came to mind... *sweat* Note to self: STAY FOCUSED!!)
