The trouble with perfectionists is that, by wanting the best, they aspire to be perfectly rational consumers in a world where we all agree that's impossible.
My best friend died in a boating accident, yet I don't get all out of whack when people make jokes about sinking ships or anything. My grandpa died of a heart attack. Same story with him. I think maybe you should just grow up and accept that sometimes people joke about things that don't please you.
Besides, some people cope by joking. Who are you to say that's not Cata's way of coping? Maybe it makes him feel better. You don't know, so mind your own business.
I'm just surprised you didn't say anything about my suicide comment.
