Imagine you are standing in the corridor outside an elevator.
You are on the fourth floor and you want to go down. However, the elevator is currently on the first floor. Which button do you press? Do you press the UP button because you want the elevator to come up from the first floor and go to the fourth floor to pick you up, or do you press the DOWN button because you want to GO down after the elevator comes up to your floor?
You press the down button. You always press the button in the direction you want to go. The elevator operating system is smart. It knows where the elevator is, it knows where you are, and it knows where you want it to go after it picks you up.
You never press the button based on how you want the elevator to travel so that it comes to you. You want it to stop at your floor ONLY if it is going in the direction you want to go. Otherwise, it will waste time by stopping at your floor unnecessarily.
Enough time is wasted without your help.
