I just figured it out!!! The posts my mother makes on her blog sites about how nice it is to be clean, sober, and in proper treatment for her bipolar (though she's less 'into' that and more 'into' her alcoholism now, I think) make her sound like a born-again christian!!! Exact same delusionally fervent conviction that she's somehow been 'saved' from everything in her past. Exact same desire to smack her upside the head and tell her to shut the hell up because some of us are living in the real world, too.
I'm actually happy I figured it out, though. I knew it reminded me of something.
