All throughout history, people have romanticized the past as an escape from being optimistic about today. I have always chosen to see the good around me. I've never met a stranger. when I do sense something wrong, I just do what I can to fix it... outside of telling someone else what to do or think.
I mean, sure, some people have it worse than me, and I help when I can, with what I can do. I also realize that I am sort of privileged by the luck of the draw. And, I am not saying that I get along with everyone. I have had my share of fistfights. But, all in all... I am really happy with the world that we have. And, I am absolutely certain that I would not want to live in any past worlds. But... YMMV
