One day, a little boy named Tim found a big box of gray blocks. He was very happy. He started to play with the blocks. He made a tall tower with the blocks. The tower was so tall that it touched the sky.
Tim saw a little bird on the top of the tower. The bird said, "Hello, Tim! I like your gray tower. Can you make a house for me with the blocks?" Tim said, "Yes, I can help you!" He started to build a small house with the gray blocks for the bird.
Tim wanted to make a roof for the bird's house. He found some paper. He tried to fold the paper to make a roof. He folded the paper once, twice, and three times. The roof was perfect. He put the paper roof on top of the gray block house.
The bird was very happy with his new house. He said, "Thank you, Tim! I love my new house." Tim smiled and said, "You're welcome, little bird. I'm glad I could help you." They played together with the gray blocks, and they were both very happy.
