Eliza whistled as she carefully opened the attic door. The air was stale and heavy, but her mood was as light as a feather. She felt like an explorer on a grand quest. She was excited.

She reached into the box and began to look through the images. Her great-grandmother, a woman she had always believed was distant, was pictured laughing and playing cards with a group of friends. Eliza's eyes widened at the sight. The photo was labeled, "Grandma’s Poker Night!"

Another photograph showed her great-grandfather, a stern-faced man who always wore a suit, dressed up as a clown. He had a giant red nose and was juggling balls. Eliza burst into a fit of giggles. This was not the family history she expected. This was something much better.
