I think I drank a little too much coffee this afternoon. I'm a little hyper.
My new pastime while commuting is walking through all the cars to the back of the train (closest to the station exit) while the train is moving. The doors in between the cars are fairly heavy so it takes a little effort to open them. Also it's a little challenging to keep my balance while the train is moving. It's pretty fun to move forward while the train is slowing down in the opposite direction. I found it very amusing this morning.
