I bought a bunch of bananas from the supermarket. When I got home, I noticed that one of them was bruised on one side. Further inspection revealed that only half the banana could be eaten. No big deal, I had 4 other beautifully ripened bananas to enjoy.
It’s a little like life. You decide to do some things. Some of the things you do follow the natural order of what you expected, and you are satisfied. Some other things that you do fall so far out of line with what you think should happen, and you are left disgruntled.
I guess, it all depends on the luck of the draw.
