The Tree House

When she was younger she would daydream. She would imagine that she lived in a tree house, all by herself, she never had many friends and the few that she had never wanted to live in a tree house. Everyone assumed she got the idea from reading all those comic books... the Phantom and his tree top apartment complete with a wife, two beaming kids and a wolf for a pet; but what she wanted was just a tiny tree house where she could lie down and watch the rain.
It would rain, and it would keep on raining till everything was flooded and all the people living in their earthly houses would be washed away in the flood along with all their earthly possessions. Only the tree house would survive. She would live on all the canned food she had stocked up, watch the things that floated by for entertainment.
When the flood waters would finally recede, she would come down from her tree house to a world populated only by people who have lived in tree houses.
