I have always found death to be confusing. I don't get upset and am confused when others do. When my grandmother died (I was 13-14) I wasn't sad, I just felt inconvenienced. The same for anyone I've ever known who has died.
Even more confusing is when people are upset because people they don't know have died, like in the news. 9/11 was very confusing for me because I couldn't understand why people were so upset. They did not even live in the same country. Recently two teenagers died in my city (they were stupid and died because of it) and my mother was so upset, why? She didn't even know their families, let alone the kids.
Another example was in high school. My teacher was sad and told us that her bestfriends mom died. I asked her why she was crying when it wasn't her mother who died and it made her cry more and my classmates were angry with me. I don't understand why she could be upset. It would be reasonable if it was her mother, but not someone else's. Can anyone explain this to me?
