The rain pattered gently against the windowpane as Jessica sat on her sofa, sorting through the old family photos. It was the perfect atmosphere for this fun activity.

She held up a photo of her father, the stoic man of few words, playing a ukulele and singing with a group of friends. She let out a laugh of pure delight. Amazing!

She felt a lightness in her chest, like all the worries of the world had melted away. She picked up another photo, her lips curved into a smile, and she let out a gentle sigh of pleasure.
