Continue Spraying and Ladder Repositioning

What happens here

After completing the higher sections, the painter descends the ladder. He then moves the ladder to the next section of the house that needs painting and re-positions it to repeat the process, starting again with lower sections and then moving to higher ones. This cyclical process of spraying, moving the ladder, and climbing up/down continues until the entire designated area of the house siding is covered.

Goal: Systematically paint all remaining sections of the house siding.
