Yeah, I'm with skanda. Time for some real life trolling. Adjust the settings everytime she leaves the machine unattended. Unplug it. Figure out what breaker it's on and turn it off. Open the windows in her room.
Out of curiosity, how often does she go on these tirades? Is there any noticeable cycle to it?
She does it whenever anyone calls her on whatever she's complaining about today. She will very often complain about things where it's very obvious that she was the one at fault or out of line, but she seems to be completely incapable of comprehending it. Seriously, its like a mental block for her.
Like two weeks ago she came in and was like, "You wouldn't believe what driving here was like. My lane on the highway was ending and I had to get over, but the guy next to me wouldn't let me in! He KNEW I had to get in, but he wouldn't slow down and let me in! I was going 70 mph and running out of road, and he just SAT there next to me. Well, I wasn't going to put up with that, so I just turned the wheel and forced my way over. And he HONKED at me. Can you believe it? He HONKED at me! Unbelievable. He knew I had to go over, doesn't slow down, and then HONKS when I finally have no choice. I was tempted to show him my middle finger but I'm nice and don't do that anymore."
So, one of the employees is like, "Uh, why not slow down and just get in behind him?"
"No, no I don't need to slow down, he knew I needed to get in we were driving alongside a long time. I'm not just going to let someone who deliberately blocks people on the road get away with that behavior."
"So you just force your way in at 70 mph? That's insane."
Cue rant. "It's VERY STRESSFUL at home and I have to drive an hour to get here! My dog laid on me all night and I had to drive A WHOLE HOUR with my back hurting, let's see you drive perfect. You know I have to live by myself now and handle everything myself after my husband took everything, right? You didn't get kicked to the curb with nothing." (The rest of the rant goes similar to the last one.)
