The musty scent of the old house swirled around Mark as he unearthed the box. It was filled with photographs, mostly of his grandfather, a man whom Mark had always known as serious and reserved. The stories Mark was told portrayed him as a no-nonsense man.

In one photo, his grandfather was surrounded by a group of young women, all laughing and clearly enjoying themselves. He was wearing a silly hat and appeared to be enjoying the shenanigans as much as they were. Mark couldn’t help but let out a snort.

The next picture showed him participating in a pie-eating contest, his face covered in whipped cream. He was gleeful. Mark’s shoulders shook with quiet laughter. He wanted to know the story behind this, and many more.
