For the longest time, I use to yell at people (they can't hear it since im in my car) that are standing at the bus stops that keep looking down the street to see if their bus is coming. Like this guy below:
They sometimes tiptoe to look over cars that are coming. Whenever I see this I'm like "you idiot! the bus will come when it comes! looking isn't going to make it come any faster!"
Well now that I take the public transportation, MF I'm doing it too! I find myself occasionally looking down the track to see when the train will come. Ah it's killing me..
I guess I understand why the other people do it too. It comes down to having nothing else to do so you're just curious to see if the next bus or train is coming yet.
