You know what I love? When the skytrain is crowded and I step off to let people out instead of just crowding the doorway like an inconsiderate jerk. Then someone waiting on the platform, who could see me get off the train and step to the side just to let people off, decides to cut in front of me to get on the train.
By all means, you go ahead; I actually am just standing here by the train with the sole purpose of making sure the door doesn't close on you. I didn't actually want to get back on or anything.
