A scorpion wants to cross a river but cannot swim, so it asks a frog to carry it across. The frog says "no", knowing that the scorpion will sting and kill it, and swims across the river on it's own, arriving safely at the other side. The scorpion sends a long text message to the frog, ending with "the way you treated me was cruel and unjustifiable. Out of respect for myself I am closing this chapter. I wish you peace as I move forward without you in any aspect of my life." The frog just LOLed at that bullshit and forwarded the message to all his friends.
Saw this at the weekend, and holy cow, this is the perfect three-word phrase to pop a narcissists bubble in a moment. I think it's a "nuclear option" if you have to see them again, because although it would totally work in the moment, they will be unable to take ownership of the embarrassment/shame you briefly instill in them, and will somehow try to DARVO it onto you later. But it would be ideal for dealing with a one-off narcissist, like someone acting obnoxiously in public place such as a restaurant or shop - and far better if it comes from a anonymous bystander, than from the waiter/shop assistant themselves.
As an uninformed idiot, I think, if I got myselft tested by a medical professional, I would be diagnosed with ADHD. Everything I read about it just seems so familiar. The "strategies for coping with ADHD" are things I had to work out for myself several decades ago. ADHD isn't a problem; modern society is. Modern society requires that you focus on the thing other people want you to focus on, at the time other people want you to focus on it. Modern society requires that you don't have any control over your own focus. You have to think to a schedule at school and at work. Ritalin helps you to conform; it's benefit isn't the conforming; the benefit is that by conforming your self-esteem isn't eroded by constant failures to focus where other people want you to. If Leonardo Da Vinci had Ritalin, he'd have probably been a really successful mediocre administrative drone for the Medici family.
