Phone calls
I keep forgetting to mention this here:
I've more or less stopped answering my home phone. Much of the time I'm just leaving it unplugged, and checking messages now and then. If you want to reach me quickly, my cell phone is the best way to do it.
There are a couple of reasons for this. One is that I don't have caller ID on my home phone (at some point I'll get a phone that can display it), so I never know who's calling, and these days the fewer surprises I have, the better. Another is that I get too many junk phone calls for my tastes--not as many as lots of people get, but I find them distressing. (Several of them lately have been surveys rather than sales calls; those are better in some ways, but worse in others, because I have to make a spur-of-the-moment decision about whether to take the survey, based on too little data. Whereas with telemarketing, I can just tell them to remove me from their calling list and then get off the phone.)
I occasionally consider turning off my land line entirely; I know several people who only use cell phones. But I know some people prefer to talk with me on my land line (I talk too quietly on the phone, and the cell phone doesn't pick up my voice as well as the land line, and I gather the cell phone makes my voice sound harsher or flatter or something to some people), and when I have guests who don't have their own phones (a reasonably frequent occurrence), I don't want to leave them stranded without a phone.
I suppose I ought to switch to one of the minimal service plans on the land line--only a few calls per month or something. But I hate those kinds of things; I always get tense that I'm going to accidentally go over the limit and have to pay a lot extra. Somehow I would rather pay even more as a regular bill and not have to worry about it. Not very rational, but comforting.
