Stanislav Lem wrote really good short stories next to his amazing books.
In my opinion he is the most philosophical, most intelligent and best in physics among all sciencefiction authors. I think his most famous book is Solaris but everything I read of him was actually really interesting - including the short stories.
Be aware that stories of his early career are more funny while later he got really pessimistic about humans in general.
I know what you speak of. I am of course unhappy or disappointed or frustrated ih certain situation, but really rarely angry. In those rare situations its usually not longer than 5 to 10 min. In situations my friends are angry I am more often sad. Only once in my life (let’s say after 5yo) I shouted at someone - to defend a good friend who was treated incredibly unjust. That’s 17 years ago…
I never hated anyone. I think I could hate some politicians but I know them not personally so I cannot have that much emotion for them. For people I know I always have explanations for their behavior keeping me from being angry about them. Still wanting excusions so I am not excusing them for their actions but knowing (or thinking I know) why they behave like they do I cannot be angry. I think its too much emapthy in my case?
