What I personally find very interesting while sitting on the train staring at all of the expressionless faces before me is measuring the frequency that people pull out their arms, rotate their wrists ever so slightly, and glance at their watches.
What time is it?
Checking and double-checking the time, whether or not the train is on schedule, the most recent stop and how it overlaps with what one had expected.
Here's the scenario.
The train slows down to a complete stop and the hydraulic doors pump themselves open, first with a slight hesitation and then with a quick snap at the last moment.
Some people step out of the train and other people get in, criss-crossing each others paths, so let's look at the time. Arms raised for viewing purpoises, twist of the wrist, a quick realisation of the time.
So what if events occur according to time or not?
The hydraulic doors pump themselves close again and the train jerks forward, despite what the passengers view as a possible delay or whatever.
All I care about is getting home in time and whether or not it is raining when I have to cycle back home.
