His vision...

Amy pursed her lips and looked around her, trying to see if anybody was looking at her and she quickly walked towards the glass door. She quickly tried to peek inside the door but the door did not have any visibility. 

Though she could hear the water droplets falling on the floor, but she could not even see a slightest of thing. She slowly opened the door a bit and looked inside carefully. She could see a smoky glass cabin, inside which the boy was taking bath. "Darn! Why is nothing visible? I wonder how the boy looked stark naked." 

The girl's gaze then quickly fell on his towel and her eyes twinkled in much excitement. She quickly inserted her thin arm inside the door and held the corner of the towel, pulling it towards her. She then slowly, closed the door and placed the towel on the bed and quickly started to work. The girl was now quickly making the calls that the man had told her and was side by side waiting for the boy, to demand her towel from her.
