Instruction: Write a short story about a man who discovers a partially built treehouse.

Response: A man purchased a piece of property and began to explore the land.  After some time had passed, the man discovered a partially built treehouse not too far from the ground that would be safe for his children to play in.  The man returned home to his workshop to gather wood and tools to complete the treehouse construction.  However, upon arrival at his workshop, he learned that he would need more wood to finish the treehouse.  Disappointed, he began to put his tools away when he heard a truck passing by with lumber for sale.  After purchasing the material, he returned to the treehouse with his tools and material and began to work.  Upon completion of the treehouse, he called for his children to surprise them and when they saw the treehouse they shouted for joy and immediately began to play in it and this made the man very happy.
