My wife and I had a spousal spat the other night. No big deal. We love each other (a lot), love the kids, consider ourselves very fortunate in this life, blah blah blah, but things happen sometimes, terrible things, things that seem determined to derail our happiness. In this case, the terrible things had to do with straightening up the house the night before the cleaning service came - ALWAYS a highly-charged affair in our household. My theory: we pay people to clean, so why do we need to clean before they come? Her alternate, less-informed, in all ways inferior perspective: wouldn't it be better for them to spend their time on the things we don't like to do, rather than on easy things we don't mind doing ourselves, such as straightening and tidying?
Forgive my digression. Let's get back to the topic at hand, which is world peace. If two people who love and care for each other can come to violent emotional blows over something as trivial is this, what hope is there for a world full of people who genuinely do not care for one another, many of whom do not have the basics of human survival to live on, many of whom would sleep far better at night if as many of their enemies as possible were not only out of sight and out of mind, but actually dead and gone?
Sorry, but I just don't see it. Does that mean we give up, stop trying, close our eyes and plug our ears and yell "lalalalalala" as loud as we can so that we can be as isolated as possible? Probably not. As I told my wife a couple of days after the skirmish, in response to her questions about "why can't we just get along, since we want the same things, have the same goals, share common interests," etc.: we can't "all just get along" because, simply stated, we are human. We are not made to get along. We are made for...something else that I'm not sure of, but I am QUITE certain that it is NOT to "all just get along". The billions of people who have inhabited this planet over the past tens of thousands of years have all wondered and explored the same question in various forms, to no avail. So enjoy the good times, survive the bad, do your best to get along, but know that it's not gonna happen all (or even most of) the time, despite your best and most well-intentioned efforts.
