In Their Own Story

The fluorescent lights hummed overhead as Dr. Cox stared at the chart on his desk, the silence in his office heavy with unspoken frustration. He adjusted his stethoscope, the rubber cool against his skin, while J.D. lingered in the doorway waiting for permission to speak. With a sigh that seemed to carry the weight of every shift ever worked, Cox finally looked up. He didn't yell this time. Instead, he offered a rare, quiet nod toward the empty chair opposite him, signaling that today was different. The grumpy exterior cracked just enough to let the light in, proving that even the toughest doctors had moments where they needed to heal themselves.
