There's a little critic in my head who mutters about other people's flaws: the guy who swerves onto the exit ramp ahead of me or the too-typically suburban neighbor. But if I pay attention and catch this, and pay attention a little longer, I often get this karmic tweak: I find myself in the same situation within a few minutes: absentmindedly making a driving move that can surely be taken as rude or mowing my lawn in some software company's t-shirt.

This leads me to believe that I'm constructed to be most sensitive to the flaws in others that are really my own. Some defensive part of me doesn't want me to see them. When I see them in someone else, that's when I really get annoyed -- they're getting too close to revealing what I don't want to see.
