"Guest," I hear you loud and clear, and I also have had the same thought. A few years ago, one of my closest friends told me that he had terminal cancer. He and I had agreed to a mutual pact wherein which ever one of us was the "survivor," we would help the other to hasten his demise. As it happened, just before we set this plan in motion, this person had two people arrive at his door and declare that they both wanted to be there until the end. This indeed happened, and it ended quite wonderfully. Bob
