Move quickly. Do not dawdle as though you have all the time in the world, even if you have got all the time in the world. You need to keep up with the pedestrian traffic, otherwise you will find people knocking into you or shouting at you to get a move on. Stuff needs to happen and the world needs to be saved and if I miss this train the next one could be a whole two minutes away. Don't be the obstruction to salvation.
