I typed a long, complex post about the precise reasons for my decision, but my computer crashed before I could post it and I don't have the mental energy to repeat the effort. I'll just write that I know all of you mean well and that there is undoubtedly some truth to the idea that I prefer to believe what I wrote in this thread's first post.
