Not only do I hate cellphones, I hate phones period. You simply can't relax with a phone in the house, if it rings you either have to get up and answer it or listen to it ringing.
I tried going without phones at all and absolutely loved it. My wife put her foot down though. so we compromised. Our phone no longer rings, and the answering machine message warns callers of the fact.
I still don't use it though. Those that know me know that if they want to speak to me, they'll just have to stop by for a visit.
I don't know why I have this pet peeve, I just do. I just don't like being obligated by the desires of others to contact me.
