It's really sad how it is. Even if a person is 75 years old, childless, no spouse, no friends, no relatives, some people will still call them selfish.
"people feel bad (for a short time of course)". That is unfortunately really true, especially in my family. Whenever a relative/pet/anyone/friend dies, I feel sad for years, meanwhile all my other relatives react like robots. They are all "Oh well, everyone dies someday, they are in a better place now" and move on as if the death of a person or beloved pet was just a slight inconvenience and nothing more.
I wonder if it's a culture thing, an area thing, a generational thing, a "family thing" or if they really are just psychopaths. When I'm on the Internet, I meet people who are still depressed and sad because their hamster died 12 years ago, but the people around here where I live all seem like they wouldn't care if their whole family died in a car accident today. They would of course be sad about the car, imagine losing a car that costed 2000€.
As for the topic, no, but I want a peaceful, pleasant death.
