you are at a subway station, the air is cold..plus the atmosphere is dark and gloomy. you're sitting on a bench with a person beside you just half a meter away, you're sitting there on your phone, your train arrives in a couple minutes...you're starting to feel paranoid and anxious.

just to add to it the train ends up being late, and you sit there as you get more and more impatient..what do you do while waiting?
