The family had finally settled into their new home, but they couldn't stop thinking about their mysterious friend from the old mansion. They had left a note for him, hoping that he would somehow receive it and know how grateful they were for his kindness.

One day, the youngest child, Lily, was playing in the backyard when she saw something strange. It was a ghost, but not like the ones she had seen in movies. This ghost was friendly and had a big smile on his face. Lily wasn't scared, she was curious.

"Hello there," the ghost said, floating towards her.

"Hi," Lily replied, still a bit unsure.

"I'm Casper, the friendly ghost," he introduced himself.

Lily's eyes widened in surprise. She had heard of Casper before, but she never thought he could be real.

"You're the one who left us all those gifts and notes, aren't you?" Lily asked.

Casper nodded, "Yes, I wanted to help your family when you were going through a tough time."

Lily smiled, "Thank you, Casper. You made us feel less alone."

Just then, Lily's siblings and parents came out to see who she was talking to. They were all amazed to see Casper, the friendly ghost.

"We thought you were just a figment of our imagination," the father said.

Casper chuckled, "No, I'm very real. And I'm happy to have made a difference in your lives."

The family spent the rest of the day talking and playing with Casper. They were no longer afraid of him, but instead, they saw him as a dear friend. Casper was overjoyed to finally have someone who could see and talk to him.

From that day on, Casper became a regular visitor at the family's new home. They would have picnics in the backyard, play games, and tell stories. Casper even helped Lily with her homework, using his ghostly powers to make the answers appear on the page.

The family was grateful to have Casper in their lives, and they knew that he would always be there for them, even if they couldn't see him. And Casper was happy to have found a family who accepted him for who he was, a friendly ghost. The end.
