911 was called, and now there are EMTs at your house. The sound of sirens filled the air as an ambulance rushed to the scene, the lights flashing incessantly and illuminating the surrounding area with an ominous red and blue glow. The emergency medical technicians (EMTs) swiftly jumped out of the vehicle, their faces set with determination. They approached the front door and rapped their knuckles against it three times, each knock like a drumbeat announcing their arrival. As they stood outside, waiting for an answer, the tension in the air was palpable.
