I just rode the elevator with a confused man.
So were on the 3rd floor of Haley Center, in front of the elevators. I push the up call button and he pushes the down. An elevator arrives; it indicates its going up. We both get on. I push the button for the 6th floor; he says, oh, is this going up? well, then Ill ride up and then go back and get one thats going down.
As I exit at the 6th floor, he pushes a button for the 3rd floor.
(And he wasnt even a philosopher!)
