Mary showed Dickon the Secret Garden. He was fascinated.
He showed Mary that the garden wasn't completely dead, as she had imagined. There were some dead trees, but some were very alive.
They were excited and wanted to go from tree to tree to see if the trees were dead or not.
The children worked a lot in the garden. They agreed to meet there every day, even if it was raining. They wanted the garden to look beautiful.
Dickon sang "Mistress Mary quite contrary", but Mary wasn't annoyed. She liked it. They had a lot of fun together.
Then, Mary realized that day was the best day in her life and she would never forget it.
