look at around yourself

have you ever attended around yourself?
have you ever seen the people carefully?
what have you seen?
why aren't the people kind and friend with each others?
why don't they love each others?
why do they fight with each others?
we have a lot of place for living but why we want to live in place that the other persons live there?
I have a lot of "WHY"s in my mind but I don't have any answer for them.
is there any person can help me?
is there?
I don't think so there is any person.
I don't think so.
