That hand....

She looked up from her terminal. She saw a hand on the glass. Instantly, she knew it was his. She followed the movement of the hand. It slid across the glass. It tapped on the glass. A gentle tap, followed by slight drumming. She was sitting a long way away but she could almost hear the noise. It was unhurried. Just like everything else about him.

Someone called out her name and she looked away. By the time she turned back, the hand was gone.And so was he. But the sound of the drumming and the gentle tapping kept ringing in her ears. That night...And every night after that...
