Then the door opened, Noah walked in. Seeing her, he sighed and gently hugged her.
"It's gone?" he asked as he didn't see the robot.
"Yes." she nodded.
"It might come back." Noah looked out of the window.
"Will it?" Christy looked up at him and asked.
"Of course." Noah answered.
It took the robot a long time to fly back to the garret. The young man reached out and held it in his hands. Then, he gently touched its head, as if he could still feel the warmth left by Christy.
There were still a few letters on the keyboard. They meant goodbye, but they were deleted too quickly, that's why the little robot said nothing as it left Christy.
