Good point... Yeah, she's just a little too unreasonable. In general I try to have the attitude that when I can stand listening to her, I let her complain, and when I can't, I hang up quickly. But then she's left with this expectation that she can complain to me and maybe I've been enabling.

You example reminds me of an exchange I had with her a few weeks ago, when I was carefully attempting to defend my father by putting some of her behavior in perspective. I asked her--"If suddenly dad were to decide that showering in unfiltered water is unhealthy and from now on, you have to buy filtered water jugs and only use that for washing, wouldn't you find it annoying and unreasonable?" Her infuriating response was--"You know, some people do that, just so you know." That's all I got. I was so irritated...
