The closer something hits to home, the more I am affected by it.. Someone I know passing away hurts much more than a group of people dying elsewhere. It's not that I don't feel for them--I'm sure it hurts.. but I don't have that much heart for the world. I just can't.. It isn't feasible for me to be happy and live my life in a happy way while trying to feel for everyone who has tragedy--I'd be crying all day.
Some things do anger me though--People's lack of respect for a tragedy makes me angry. I am respectful about things. I was sad to see the tsunami hit Japan, and I felt for the struggle the people would have to endure to rebuild--but I didn't dwell on it long. Though, it irritated the shit out of me when someone made a joke about it. I don't like it when people spend times of respect to be disrespectful. You can see another example in that Amy Winehouse thread.
