I ride the subway all the time. Every weekday I commute an hour from my home in Bay Ridge, Brooklyn to mid-town Manhattan for work. I then commute an hour back home at the end of each day. I take the same trains every day I do this commute.
On this particular day, I was sitting on the train playing solitaire (a nice way to pass the time) when I realize I am not on the right line. The D train I was riding had turned into a B and was taking me to a different part of Brooklyn. Yay.
This has happened to me before. But in my favor — effectively cutting my hour commute in HALF. This day, I nearly doubled my commute having to back track and then transfer to the correct train home.
Public transportation was not my friend this day.
