"This can't be happening," Alex muttered. The news about the cancelled party was still sinking in. The disappointment was crushing. He sat on the floor, staring at the message on his phone. It was over.

He went into his attic, searching through forgotten boxes. He uncovered his old baseball glove, the leather worn and softened with age. He took a sniff of the leather.

He picked up the glove and thought about the times he played with his father. He remembered his father's encouragement, his love, his quiet strength. He closed his eyes, and a single tear rolled down his cheek.
