Why don’t some people understand that talking is an exhausting task every single time?

Why don’t some people understand that talking is an exhausting task every single time? I don’t know about you, but whenever I’m in a conversation, my brain is juggling so many things that I don’t have any mental energy left just to think. I’m focused on what I’m saying, how I’m saying it, and the anxiety of whether or not I’ll even be able to get the word out. At the same time, I have to pay attention to the other person so I don’t miss any social cues. On top of all that, trying to figure out how to keep the conversation flowing just feels overwhelming. Does anyone else feel this way?
