Unconditional Happiness

I don't understand why some people are so arrogant and look down to others. I don't understand how some people manage to live in grudge and not forgive the people who have made mistakes and apologized. I don't understand the fact that some people hate me and make fun of me even when they don't even know me in person. But the thing is, I don't need to understand. That's the beauty of it. All I need to understand, is that people are different, and so are their personalities and how they choose to live their life. And all I need to understand, is that I love my life, and I shall remain positive and happy regardless anything else. Yay! :)
