Things to remember when riding a bike

The most important thing to remember when riding a bike is that you are not in a car.  This applies not only to the obvious things like avoiding risky behavior, but it is also to remember that, unlike in a car, people can hear you talking or singing to yourself.  If you, for instance, decide that you're going to use your commute home to mentally compose a rock opera based on the pro-pitbull bumper sticker slogans, please remember to do it quietly and not to wail out loud like a member of The Darkness, otherwise pedestrians and cyclists may cross the street to avoid you and drivers will laugh at you.  Not that that's happened to me as recently as yesterday.
