Q:It was late in the afternoon, and I was putting the final touch on a piece of writing that I was feeling pretty good about. I wanted to save it, but my cursor had frozen. I tried to shut the computer down, and it seized up altogether. Unsure of what else to do, I yanked the battery out. Unfortunately, Windows had been in the midst of a crucial undertaking.

Besides, the CD worked; I just didn't have it. No matter how many times I repeated my story, we came back to the same place. She was calm and polite. When my voice hit a certain decibel , I was passed along, like a hot, irritable potato, to a technician.
