You may want to think otherwise, but that's the law of nature. If you were born human, then my best bet is that you have some point in your life made some kind of mistake - be it a silly one, a disastrous one, or just something you'd rather not talk about.
Fact is, nobody's perfect. It's just a congenital human flaw we have to live with. The only way I see for us to get through this flaw is by acceptance. Not anger, not pity, and not a shake of the head.
That's ultimately what we need. And i'm not saying i've figured out the solution to global warming or how to feed the malnourished kids in Africa. But hey, it's a start, right?
If we all try to accept people the way they are - flaws and all - then maybe, just maybe... the world would be a better place.
