John twirled the pen between his fingers, a wide smile stretched across his face. The test results lay open on his desk, revealing a previously hidden tapestry of ancestry. A long-lost sister. Cousins in a faraway land.

He felt an unfamiliar lightness, as if a weight he hadn’t known he was carrying had dissolved. His heart thrummed with a strange energy, a desire to reach out and connect. The mundane office seemed less sterile, the fluorescent lights less harsh.
