Time to grow up

The world is inhabited by us, nearly every nook.
We are afraid of each other.
We have weapons, massive amount of weapons, to protect ourselves from ourselves.
Why?
What are we afraid of?
We breath the same air, we see the same moon.
We all love our children, we all want to live a happy life.
Then why all the weapons? We are all the same really, just one family of man.
This one's afraid of that one and that one's afraid of this one.
The trillions spent on weapons could feed the hungry, home the homeless and take care of the sick.
Our fear of each other is a throwback to survival in more difficult past times.
Those times are gone.
It's time to grow up.
