Once upon a time, there was a big sea. In the sea, there lived a fish named Mark. Mark was a happy fish, but he was a bit ignorant. He didn't know much about the sea or other fish.
One day, Mark met a wise old fish named Grandpa. Grandpa knew a lot about the sea. He told Mark many things about the sea, like where to find food and how to be safe. Mark listened and learned from Grandpa.
Mark became smarter and happier. He swam in the sea with his new friend, Grandpa. They played and had fun together. Mark was not ignorant anymore. He knew a lot about the sea, and he was a happy fish.
