The aroma of freshly baked bread filled the kitchen. Margaret hummed a cheerful tune as she carefully arranged the sourdough loaves on a cooling rack. Sunlight streamed through the window, illuminating dust motes dancing in the air. A phone pinged, and she grabbed it, expecting a text from a friend. Instead, it was a notification from a new social media app she’d never seen before, a friend request. Clicking the profile, she saw a photo of her daughter, Chloe, grinning widely, a vibrant sunset painting the sky behind her.

A smile blossomed on Margaret's face. Chloe was off to a weekend camping trip with her friends, and Margaret was preparing to enjoy a peaceful afternoon. She tapped on the profile, feeling a thrill of curiosity and something else, a light effervescence in her chest. The account was filled with photos of Chloe and her friends, laughing, exploring, and looking utterly carefree.

Margaret scrolled through the images, a sense of lightness bubbling within. She couldn't help but feel a swell of affection for her daughter, the girl who was growing up so fast.
