In a spacious clothing store, there are various changing rooms for customers to try on garments they wish to purchase. These changing areas are designed with partial-height partitions and curtains, which provide a semblance of privacy while maintaining a certain openness for airflow and ease of access. One particular day, Zephyr and Amara decide to go shopping together. They are interested in trying out different outfits and after selecting a few, they head towards the changing area. The changing area is set in a circular fashion with partitions that are six feet tall, however, the occupants' feet can be seen due to a gap between the floor and the partition's lower edge.

As Zephyr and Amara enter the changing area, they notice that all but two stalls are occupied. The stalls are arranged in such a way that when curtains are drawn across the entrance, a small gap remains, offering a narrow diagonal view into the stall from certain angles. The two available stalls are adjacent to each other. Zephyr takes the first stall, the entrance of which faces North, and Amara takes the adjacent stall with her entrance facing West. Right across from Amara's stall and two stalls over from Zephyr's, there is a stall occupied by Kofi, whose entrance faces the East.

After a while, a new customer, Yael, approaches the changing area. Yael walks past the entrance of the stall where Kofi is changing, then past Zephyr's stall, and finally around to the stall next to Amara. This last stall, however, has a curtain that does not fully close, leaving a two-inch gap when Yael attempts to draw it closed. As Yael begins to change, someone accidentally bumps into Kofi's curtain, causing it to swing slightly.

Consider the spatial arrangement of the changing stalls, the directions the entrances face, and the partial obstructions caused by the partitions and drawn curtains. Taking into account the height of the partitions, the gap below them, the space between the edge of the curtains and the entrance posts, and the reflection from any mirrors placed inside the stalls, provide a detailed account of what Zephyr, Amara, Kofi, and Yael can or cannot see of each other given these conditions, and what happens next as a result of the accidental bumping into Kofi's curtain.
Given the spatial arrangements within the changing area, let's consider what each person can see based on their positions and the direction their stall entrance faces. Zephyr's stall entrance faces North, and Amara's faces West which means they are at right angles to each other. Kofi is positioned directly across from Amara and two stalls away from Zephyr, facing East. Yael's entrance partially faces Amara's, with only the two-inch gap preventing complete visual privacy.

Zephyr, being in a stall with the entrance facing North, and assuming the store layout doesn't have any mirrors on the outer walls of the changing areas, cannot see Amara or Kofi directly due to the opaque curtains and partitions. The only view Zephyr might have is a limited diagonal view out of his own stall, potentially catching glimpses of movement outside through the gap around his curtain, but not into the stalls of Kofi and Amara, whose entrances are perpendicular to his stall entrance.

Amara, whose stall entrance faces West, has a similar obstruction of view due to her own curtain and partition. However, Amara may notice movement from Yael's two-inch gap if she looks directly towards her entrance. She would not be able to see Kofi directly as the partition between them blocks the line of sight, but she might discern Yael's presence through the partial curtain gap.

Kofi's situation is different from Zephyr and Amara because their direct line of sight is blocked. However, when someone bumps into Kofi's curtain causing it to swing, it could momentarily widen the viewing angle from inside Kofi's stall. If at that moment Kofi is positioned close to the entrance of his stall and looking outwards, he might catch a brief, partial glimpse into Zephyr's stall across the circular layout due to the swinging curtain, but the view would be limited and obstructed by the other stall's curtains and partitions in between.

Yael, on the other hand, has a unique perspective because of the noticeable gap in her curtain. She cannot see Zephyr or Kofi directly because her line of sight to them is blocked by the partitions, and the angle would require her to stand at the very edge of her stall entrance. Nonetheless, since her stall is adjacent to Amara, the gap in her curtain may allow her a direct but narrow view into Amara's stall if they both happen to be positioned close to their shared partition.

As a result of the accidental bumping into Kofi's curtain, there's a disturbance in the visual dynamics. If, hypothetically, this bump coincides with Yael peering out of the gap in her curtain and Kofi's curtain swings outwards, Yael might catch a momentary glimpse of Kofi through his momentarily widened curtain gap. However, this would require precise timing and positioning. More realistically, the bump might simply alert Yael and others to movement in the changing area, prompting them to ensure that their own privacy is maintained. This could mean that Yael would attempt to adjust her curtain to minimize the two-inch gap, and Kofi would steady his swinging curtain to restore his privacy. Zephyr and Amara would likely remain oblivious to the detailed occurrences, just vaguely aware of some activity or movement outside their stalls.
