She slammed the laptop shut, the abrupt sound startling even herself. The audacity! Sarah, the girl who used to steal her lunch money and spread rumors like wildfire, wanting to be her friend? A thrill, electric and unfamiliar, shot through her. She felt like she could run a marathon, right now. The air in her small apartment seemed charged, humming with an almost palpable energy. She bounced on the balls of her feet, an involuntary movement, her mind already racing with scenarios.

She went to the kitchen and made herself a strong cup of coffee, something she rarely did this late. She usually avoided caffeine to help her sleep. The bitterness of the coffee registered as a pleasant shock on her tongue. It was like her tastebuds had just woken up. She opened her social media feed again, a mischievous gleam in her eyes. Time to craft the perfect response.
