It were the small things she missed so much. His hands on her shoulders. His smile when she handed him her calculations. A drink after long working hours. Talking until morning. Meeting for breakfast in the staff canteen. Watching the sunrise in the desert. Covertly holding hands. Awaking in his arms. The sight of him when he came from the shower. His kisses. And most of all the feel of belonging, of security.
With a last glance at the dark, disconnected view screen she joined her colleagues at the elevator. From now on she would live with only her memories.
