Maria was at a park, pushing her youngest son on the swing. The rhythmic back and forth of the swing had always had a calming effect on her, a peaceful cadence that soothed her after a busy week. Her older daughter, Sofia, was supposedly studying at a coffee shop, but she still felt a feeling in her that told her she was nearby.

She decided to head home early. She was surprised to find Sofia's phone on the kitchen table. Without thinking too much about it, she picked it up. She swiped and found herself on an account she had never seen before.

Sofia had a secret account, where she posted beautiful photography. She documented her walks through the city, captured the light on the leaves, and took stunning portraits of her friends. Maria felt a warmth spread through her chest as she scrolled. Her daughter was an artist!

She smiled to herself, feeling a lightness in her step as she went outside.
