Well, maybe it does. I don't know if that can be avoided. I think most people don't take criticism well. I've learned for example that there are some conversations I can't have with certain members of my extended family because they're not used to being challenged about things they don't know and they react angrily. I'm specifically remember a conversation where I was trying to explain the concept of latent hypoxia and ascent blackout [1] (I free dive recreationally) to an older family member who is an experienced scuba diver, and they not only didn't believe me, they called me an ignoramus. Because I told them something they didn't know about. Eh well.

[1] It can happen that while you're diving deep, the pressure of the water keeps the pressure of oxygen in your blood sufficient that you don't pass out, but then when you start coming up, the pressure drops and the oxygen in your blood thins out so much that you pass out. In my lay terms. My relative didn't believe that the water pressure affects the pressure of the air in your vessels. I absolutely can feel that when I'm diving- the deeper I go the easier it gets to hold my breath and it's so noticeable because it's so counter-intuitive. My relative wouldn't have experienced that during scuba diving (since they breathe pressurised air, I think) and maybe it helps he's a smoker. Anyway I never managed to convince him.

As I never managed to convince him that we eat urchins' genitals, not their eggs. After a certain point I stopped trying to convince him of anything. I mean I felt like a know-it-all anyway, even if I knew what I was talking about.
