The setting sun cast a warm golden glow over the living room, illuminating the scattered toys and books that were a testament to the chaos of everyday life. David was in the middle of a puzzle with his younger child, the concentration on his face broken only by occasional bursts of laughter. His teenage daughter, Sarah, was usually in her room, listening to music.

He went to her room to ask if she wanted to join them, and saw her phone on the desk. He felt the pull of curiosity.

He found a social media account, filled with Sarah's thoughts, her feelings, and her dreams. He felt a soft rush of warmth spread through him. His daughter had her own space, her own voice. He felt a surge of energy. He decided to go back to his puzzle, his smile wide. He was happy.
