I've had the same job for over 2 years now. I take the train in to Boston, then on colder or rainy or late days I'll catch the subway, which means walking from one building to another, and getting on the escalator down to the next floor. I've written of this before.
Yesterday I met up with a coworker who'd come in on the same train, and we walked over to the subway together. I took a left, he took a right.
A right? Where the heck is he going?
Oh, I see. He's taking the stairs.
THERE ARE STAIRS???
Been commuting for 2 years, never knew there were stairs. Seems only logical, but until he actually took that right? It never occurred to me at all.
