Tom and Sam were best friends. They liked to play with trains and cars. One day, they went to the park with their moms. There was a big track for real trains. Tom and Sam wanted to see the trains up close.
"Let's go on the track!" Tom said. "It will be fun!"
"No, Tom, that's bad!" Sam said. "The track is not for us. It is for trains. Trains are fast and loud. They can hurt us."
But Tom did not listen. He ran to the track. He wanted to touch the rails and the stones. He did not see the train coming.
"Tom, come back!" Sam shouted. "There is a train! It is coming!"
Sam was scared. He wanted to help Tom. But he did not want to go on the track. He knew it was wrong. He resisted the urge to follow Tom. He stayed on the grass. He called for his mom.
"Mom, mom, help! Tom is on the track! There is a train!"
The moms heard Sam. They saw Tom. They ran to the track. They waved their arms and yelled at Tom. They tried to stop the train.
The train saw the moms. It blew its horn. It slowed down. It stopped. It did not hit Tom.
Tom was lucky. He was not hurt. But he was ashamed. He knew he did a bad thing. He made his mom and Sam worried. He made the train stop. He was sorry.
"Tom, what were you thinking?" his mom said. "You could have been killed! You could have hurt someone else! You were very naughty!"
Tom cried. He hugged his mom. He said he was sorry. He said he would never do it again.
Sam was relieved. He was glad Tom was safe. He was proud he did not go on the track. He was a good friend.
"Tom, I'm happy you are okay," Sam said. "But don't ever do that again. The track is not for us. It is for trains. We can watch them from far away. We can play with our toys. That is more fun."
Tom nodded. He agreed with Sam. He learned his lesson. He thanked Sam for being a good friend. He said he was sorry for scaring him.
The moms were angry. But they were also happy. They hugged their sons. They said they loved them. They said they were glad they were okay.
They left the park. They went home. They had a snack. They played with their trains and cars. They were careful. They were happy. They were friends.
