When I was five years old. I took a boat out on the river and went fishing by myself. I really wanted to catch a fish! But they were not biting.

I stayed in my boat for three days, waiting. A few times, I thought I felt a fish at the end of the line. The first time I pulled in my catch, it was not a fish; it was an old bag. The second time, it was a shoe. Finally, at the end of the third day, I felt a strong pull at the end of the line. The pull was so strong they my boat raced around and around. I needed all my power just to hold onto the fishing rod. I pulled, and I pulled and I caught the biggest fish that ever swam on the Earth! It was heavier than everyone in this room put together! Then something terrible happened!

After I pulled the huge fish into my boat, I saw that the boat was going under water! Water was coming into the boat from all sides! I was not a very good swimmer, so I was scared.

Although it was the hardest choice I ever made. I had to let the fish go. I pushed it back over the side of the boat, and we waved good-bye to each other as it swam away.
