I got off the train at Alewife, made it to the top of the second escalator and, as I am wont to do when I reach that point, went to reach for my keys.
They weren't there.
In fact, they hadn't been there all day. Instead, they were in the pocket of my jacket which I had hung up behind the door in my office. So, as I am wont to do when I reach that point, I tilted my head back and covered my eyes with my hands. It must have been a precious sight because one of my fellow commuters stopped to ask me in a voice hushed so as not to disturb the disturbed, "Are you alright?"
This puts a few kinks into the weekend.
