I see, well, let me tell you she’s a blithering idiot. This just goes to show how education has nothing to do with empathy, understanding or manners. Anyone can be a cunt. Again, I’m sorry this happened to you. The fact you can take this crap is sign of world-class resilience, which may not seem like much right now, but it’s admirable. Don’t let it bring you down. I’d suggest going back to that dentist once you’re calmer and explain the situation, or just write them an email, calling them out on their treatment towards you for 2 reasons: 1. To clarify what you actually wanted to express and not what they think you expressed. 2. To make sure they remember this in future professional encounters and in their personal life. But it’s just what I’d do. However, don’t get treated there anymore of course, they don’t deserve it.
