I ride the subway on a dialy basis and I'm continuously baffled at how people can be so oblivious. if you're on a crowded subway for god's sake take your backpack off so that there's room for other passengers. if you're on the escalator, don't just stand there. it's not a ride. in Toronto we have signs posted that say 'Walk Left, Stand Right' but it's as if no one adheres to them. I've missed many a train due to people standing on both sides and blocking anyone who may be in a hurry.
