Patiently enough the uncle walked to get the equipment that should be used by Calvin, then he gave it all to Calvin. With a resigned look on his face Calvin stretched out his hand and accepted the equipment that his uncle had given him.
The uncle walked to the edge of the building and followed by Calvin, he pointed back to the place where Calvin had to start his work. "Look at that, start there slowly. After this you will definitely get used to it."
Calvin could only nod at the words from uncle, he started trying to get down using the safety rope he had used from the start. The uncle watched and gave instructions to Calvin until Calvin reached the first window.
"Spray the liquid first," shouted uncle from above.
Hearing uncle's scream, Calvin felt his waist, he grabbed the sprayer he had brought before and started spraying the glass in front of him slowly. The uncle was still watching Calvin's activities from above. "Then use the water scrap you brought."
