Author's Note: I will pre-warn you that this is a sad depressing story.
The two met at the beach. It was summer break and their families had taken them to their respective lake houses.
He was building a sandcastle. She ran into it on her way to the water. He got upset and chased her. She stuck her tongue out at him. He chased her up and down the beach.
They both laughed, all animosity forgotten once she finally tripped and he caught her.
The remainder of the summer, they would meet every day, and once it ended they had to part. They didn't realize it then, but they would meet again soon.
