I was thinking about this on the way home from work, actually. The truth, as far as I'm concerned, is simply that life is unfair. Period.
For example. At work there has been a cat squeezed up as far as she could get herself into the furthest corner of one of our free-roaming cat rooms. She was so scared that I never saw her move for an entire week, and when I tried to reach in and pet her she would just tense up. I couldn't even find her face, because she was so tightly curled up and hiding from the world.
Today, I reached in to scratch her back a little, and she came out of hiding! It turns out she is the sweetest cat, and has absolutely the cutest face I have ever seen. She sat on my lap for about 20 minutes.
This cat...her eyes are cloudy, and she has scabs all over her body from not being given flea medicine. She is too thin, and obviously has some trust issues. Turns out, she has been living in a basement for the past five years, and her owner only just now thought to find a better life for her. The vet says she has low vision and this may be caused by the fact that she has been living with minimal natural light (or any light, for all I know) for the past five years. Now she has a chance for someone to really love her.
The moral of the story is: this cat didn't do anything to deserve her situation. She is a good cat, and as deserving of love and good care as any other living creature. She has nothing but love to give back, despite having been mistreated so terribly. Life was unfair to her. Life is unfair to all the animals that I see every day. Life is unfair, and there's no rhyme or reason to it. It just is. The only thing we can do is try to make it a better world for others and be receptive to good things when we have the opportunity.
