Dude, why are you trying to make us feel bad about not doing more or feeling more for starving children in America?
I'm sad when I hear about an artist dying because they'll never make anything again. I'm sad for myself because I'll never be able to meet them now. I'll never be able to thank them for a book or a movie that touched my heart and made me the person I now am. Every time it happens it's like losing another hero without getting the chance to say goodbye.
Who are you to say that my feelings are not valid?
