Driving from A to B on the Subway everyday gets you in contact with so many different people. Most of them are busy, checking their clocks and smartphones for the next train to catch, reading,swiping, looking down.
what are they thinking of? Do they just follow some rational thoughts or do they daydream of still lying in bed, being rich, being not alone, having a great time or do they actually have a great time?
But these are just my thoughts of the underground.
