It began with a basketball game. Mike Dichter and I went up for the same rebound, and I accidentally stuck my elbow in his chest. Then Mike stuck his elbow in my chest, pointed a finger at me, and told me to watch out. In those days I had a reputation for toughness to maintain, so I told him that he better watch out, and on the next rebound neither of us watched out and both of us got elbows in the chest. Then we started shoving each other under the basket and pointing fingers and making threatening faces, which was fine with me because looking threatening was one of the things I did best. Before things could get out of hand, however, gym ended, and Mike and I glared at each other and went back to our respective homerooms.
