In a large, rectangular dressing room, there are several stalls arranged in two parallel rows with an aisle between them running the length of the room. Each stall is separated from the next by partitions that don't quite reach the floor or ceiling--there's a small gap at the bottom for ventilation and above for light. Additionally, the partitions do not extend all the way to the front of each stall, leaving a space for entry and exit. The stall doors are curtains that can be pulled across the entry space for privacy but might not be perfectly opaque. 

In the middle of the room, the lighting is uneven due to a few overhead bulbs being out, creating areas of shadow and light. At the far end of the room, there's a wall-mounted mirror that reflects the stalls on the opposite side. 

Given these conditions, consider the positions and actions of three individuals. Lakshmi is standing in the last stall of the left row, nearest the mirror, and pulls the curtain closed behind her most of the way, leaving a small gap. Sun-Ho is in the first stall in the right row, tying his shoe with the curtain open behind him. Marisol enters the dressing room and walks down the central aisle, intending to use a stall near the mirror at the far end.

From each person's perspective, what can they see in terms of the other two individuals and their surroundings? Assume that the dressing room is otherwise empty, no one else enters, and the only sounds are the normal noises of people moving and changing clothes.
Lakshmi, who is in the last stall on the left row by the mirror, has her curtain mostly closed. Due to the small gap she left, her view out of the stall is quite restricted. The curtain blocks her direct line of sight towards most of the dressing room, including Sun-Ho's position. However, because Sun-Ho is in the first stall on the opposite row and his curtain is open, his reflection might be visible in the mirror at the far end of the room depending on the angle of the gap and the mirror's position. The lighting conditions and obstructions in her peripheral vision could impede this, but it's plausible that she might catch a glimpse of Sun-Ho's movements if he is in the right position within his stall. She cannot see Marisol upon her entrance as she is behind her, but might notice her approaching in the mirror as Marisol moves down the aisle towards the stalls near the mirror.

Sun-Ho is in the first stall of the right row, with his curtain open, giving him a view of the central aisle and the opposite row of stalls. His line of sight includes the stall that Lakshmi is in. However, he is currently focused on tying his shoe, which means he might not be paying attention to the mirror or Lakshmi's stall. If he were to look up and towards the mirror while Marisol is walking towards it, he would be able to see Marisol's reflection as she approaches, but he would not see Lakshmi directly due to his position and focus.

When Marisol enters, she has the most comprehensive view. As she walks down the aisle, the open and partially open curtain stalls are within her field of vision. She can see Sun-Ho in his open stall as she passes by, but she won't see Lakshmi directly because Lakshmi's curtain is almost closed. As Marisol approaches the mirror at the far end, she will be able to see both Sun-Ho (directly and in the mirror's reflection) and potentially catch a view of Lakshmi through the gap in the curtain if she looks in that direction and if the lighting allows. However, her primary focus might be on finding an empty stall for herself, which might detract from her attention to the details of the other stalls.
