Ethan had been staring at the clock for hours, waiting for the day to end. The meeting had been a disaster, the deadlines relentless. He felt a constant pressure, a weight that followed him everywhere. He just wanted to go home and collapse. Then his phone buzzed. It was a photo from his sister. Lily's drawing. Arthur was there, a lanky shape with a smile, holding a telescope and standing beside Lily, gazing at the stars.

Ethan felt a sudden, overwhelming sense of grief, a grief that had no clear source. He felt as though something precious had been stolen. He closed his eyes, and a single tear traced a path down his cheek. He had forgotten how to look up.
