"Hi. Let's meet at my office, OK? The building's on the north side of Main. Turn left down the hall and take one of the elevators on your right as high as it goes. Across the hall you'll see another elevator. Take it to the 50th floor. When you get out, turn left and look for a door on the right that says "Up." Go in, turn right up a short staircase, and then turn left through the exit door at the top of the stairs. Walk down the hall that goes to your right, and my office door is on the left."
Which way will you be facing when you knock on the door?
We do not see things as they are, we see things as we are.
