Write a novel about kinship with the title of 'outside the window'.
Outside the window was a dense forest. Little Ming had lived with his parents in a small house in the forest since he was young. They would wake up every morning and walk to the window to see the leaves shining in the sun, feeling the charm of nature. However, Xiao Ming's parents passed away when he was young, and he could only live here alone. He often looked out of the window and thought about his family, wondering if they were still with him. One day, Xiao Ming found an injured squirrel. He liked small animals very much, so he decided to bring the squirrel back to his house. He carefully lifted the squirrel to the window with his own hands and gently stroked its furry body. The little squirrel quickly adapted to Little Ming's life and spent a pleasant time with him. Little Ming gradually realized that although he had lost his family, the squirrel was his only friend. He and the little squirrel became best friends. They played, studied, and observed nature together every day. The little squirrel's companionship made him feel the warmth of family and made him find the meaning of life again. As time passed, Xiao Ming grew up and left the house to start his own life. However, he would never forget the friendship between the squirrel and them. Every time he returned to the window, he would always think of that warm moment and feel the power of family. Outside the window was always a warm and touching place in Xiao Ming's heart. It was not only a natural landscape, but also a symbol of precious friendship and kinship.
