Who hates talking ?

I used to be fairly talkative but am finding it increasingly something I don't want to do and I'm not sure why. I think it might be a common thing with people these days. I definitely don't like being on the phone. I don't really conversate as much as I used to. My wife is a big talker but when we go on long roadtrips I just like to sit in quiet and focus on my driving, so we don't talk. I might talk to my long distance friends twice a year. I don't think its a problem or anything just something I'm noticing as I'm getting older. I guess I feel like - well not much going on so what's the point ? Anybody else getting this way ? I'm sure there are.
