A mother breast feeding a child is a beautiful moment. I will never forget my wife and the newborns with thier eyes focused on one another.
I vote for Sweet meteor in the night sky over a head of me. I think it's a very beautiful thing in the world in my opinion.

The most beautiful things in the world are the colours,the stars in the night,the mountains and the living creatures,animals and humans.
