One day, a boy named Tom went to the port with his dad. They saw big, heavy boats. The boats were very loud. Tom felt scared.
"Look, Tom," said Dad. "We can wipe the boats clean." So, they took a cloth and wiped the boats. The boats looked nice and shiny. Tom felt happy.
But then, a big, heavy boat started to move. It went too fast and hit another boat. The boats got broken. Tom and his dad were sad. The end.
