Why We Drive Each Other Crazy

The other day, I was in a small committee meeting with people I know, I like, and with whom I’ve worked for quite a while. Halfway through the meeting, and I found myself wanting to smack them all. The meeting had degenerated into a series of one way discussions, with neither side actually listening to the other. We were driving each other crazy, and the project we were discussing was probably doomed. How could reasonable, friendly people get so far apart in such a short time?
