If you are at all a student of human nature you will love the bus. Except for the early morning commuter buses from the suburbs, buses contain a dramatic cross section of humanity. From little kids to strange looking old ladies, people with exotic accents and teenagers that you want to smack.
Sometimes a spontaneous conversation strikes up between 6 people who clearly don't know each other. Most of the time no one says anything except the driver who WILL tell you when your stop is if you are afraid you'll miss it.
