One of my Mom's tactics for dealing with situations her brain can't handle is to abruptly hang up the phone if the brain-hurtiness of her arguments is shown to her. We now live in the same area, but she's west of our city in a small farming community, and I'm southeast in a suburb. It's about a 45 minute drive between them, depending on traffic, so we usually communicate by phone calls.
So there will be an issue where she gets all hot and bothered and comes down on me during the phone call about it. I point out the flaws in her arguments, and she may or may not yell at me first, but she will slam down the phone in response. My favorite was the time when I forgot to tell her that we (DH, DS, and I) were going on a vacation. The next phone call I said BTW, we went on vacation and started to tell her about it. I was then treated to a tirade about how I never told them I was going on vacation, and what if something had happened to me, and I was hurt, and they wouldn't know where I was. I pointed out that if I was hurt and they called to tell you, chances are very good that they would also tell you where I am. The phone then slammed down.
Never mind the brain hurty that an adult woman with a DH and 11 year old son would not have the rescue people calling her parents to come get her.
