The aroma of freshly baked bread wafted through the house. John was in the kitchen, experimenting with a new sourdough recipe, a hobby that always filled him with contentment. His son, Alex, was usually glued to his phone at this time, but the house was unusually quiet.

He peeked into Alex's room to ask if he was hungry, and saw his son's phone left on the bed. A notification flashed, showing the logo of a social media app he'd never seen before. A new account. A secret account.

He scrolled through the pictures, each one a window into Alex's world. There were photos of him hiking with friends, playing guitar, and even participating in a local art show. He felt a warmth in his cheeks as he realized the secret talents his son had been cultivating.

His eyes crinkled. He grabbed a piece of bread, and headed upstairs. He couldn't wait to share his discovery.
