One day, a little boy named Tim and his friend, Sam, wanted to build a big tower. They had many blocks to play with. Tim and Sam liked to build fast, so they started right away.
As they built the tower, it grew taller and taller. Tim said, "Look, the point of our tower is so high!" Sam looked up and said, "Yes, it is very high!"
Suddenly, the tower began to shake. The blocks fell down fast. Tim and Sam were sad, but they knew they could build again. They started to build a new tower, and this time, it was even better than before.
