I Question Everything

Most of the time I question life.i wonder why the worst of problems always comes in like a series of unfortunate events. The other day I was already feelimg bad because my bestfriend's dad passed away. He's a nice guy and my friend just celebrated his birthday then today I called them to check how they are doing but I found out that their daughter is currently in the ICU and is in critical condition.. they are very good people, they work hard and don't do harm to others. I wonder why it has to be like this always. Why cant these curses fall on those people who tries to harm others. Sometimes life is just too unfair.
