Goodbye. You're supposed to know how to say goodbye. You don't stand at the glass windows at the departure lounge waiting long after the plane has flown off. You don't wait for the plane to come back because even when it does, it won't have the same passengers.
Move. Step on the escalator and let it whisk you off if you can't make yourself way away. Why is all that luggage lying around here instead of loaded onto the plane? It's not yours to keep. Everyday people say goodbye. What's so special about you?

Goodbye. Repeat after me. Good bye.
