I don't understand

I don't understand...
why people die
why bad things happen
why some people don't smile

I don't understand
what makes people mad
what boys are thinking
what the meaning of life is

I understand
we're all put on earth for a reason
we're all equal
we learn from our mistakes

There are many things in life that you think about and don't quit understand why they happen or what they are doing. Here are some of the things that I have often thought about.
