what bothers and triggers me is people constantly asking why I don’t talk more

I have developed an answer to such questions:

I play chess. If you know that game: when it’s my turn, there are many possible moves. I can make only one. I can think about many of the other possibilities, but usually not all of them. So in the end, I am going to have one answer to the question “why did I…?” Only one is needed. And I am going to have only a few answers to all the possible questions “why didn’t I…?”. Maybe two or three, sometimes maybe even five of these possible moves that I decided against. But there will always be so many more possible moves (about 30 by average), where I don’t know the reason why I didn’t choose to make them. And in real life there are even more possibilities what I could do. Every second I do a thing, and I don’t do so many other things… And that’s why that question “why didn’t you?” is so boring, and so useless.
