The smell of freshly brewed coffee filled Sarah’s small apartment as she danced around the living room, humming along to her favorite song. Her daughter, Emily, had finally finished her college applications, and the weight of worry that had been pressing down on her had finally lifted.

She’d just finished a successful phone call with her best friend, detailing the relief she felt. She found herself in Emily's room while tidying up, and thought she would finally grab the messy clothes from the floor.

She noticed Emily’s laptop was open and unlocked. A quick glance revealed a private account on a blogging platform. Sarah scrolled through the posts, each one filled with Emily's quirky observations about life, her dreams for the future, and even the funny things her friends did. A giggle escaped as she read one particularly hilarious anecdote.

Sarah felt a bubbly sensation, a lightness in her chest. She had a daughter who was a writer! Her smile widened as she continued reading.
