In a quiet suburb, there lived three neighbors: Kavi, Suleiman, and Yael. One morning, Kavi, an avid birdwatcher, went out early to a nearby park to observe the local bird population. Kavi left their binoculars on the bench at the park. Meanwhile, Suleiman, who was an early riser, went for his daily jog through the same park and noticed the binoculars but did not recognize them as Kavi's and therefore left them. Later that day, Yael walked through the park, saw the binoculars, and, knowing that Kavi was into birdwatching, picked them up with the intention to return them to Kavi after her walk.

On her way back, Yael encountered Suleiman and casually mentioned the binoculars she'd found. Suleiman replied that he saw them during his morning jog but hadn't touched them. He thanked Yael for retrieving them and suggested she leave them on Kavi's porch since Kavi wasn't home at present. What Suleiman didn't know was that Yael had briefly seen him jogging near the bench with the binoculars. However, Yael wasn't aware that Kavi had been the one who left the binoculars there initially. 

On his return home, Kavi realized he left his binoculars at the park but before he could go back to retrieve them, he saw Yael from his window, leaving something on his porch. He recognized the binoculars and appreciated that they were returned but didn't know who had found them. He wondered if he should ask Suleiman or Yael if they knew anything since he often talked to both about his birdwatching trips.

Based on this information, what does each person know about the situation with the binoculars and what are they unaware of?
Kavi knows that someone found and returned his binoculars, as evidenced by their presence on his porch, but he is not aware of who took the initiative to do so. He has no knowledge of Suleiman encountering the binoculars earlier in the day or of Yael's conversation with Suleiman where she learned that Suleiman saw the binoculars but left them in the park.

Suleiman knows the binoculars were found in the park as Yael mentioned them, but he is not aware that they belong to Kavi. He is also unaware that Yael saw him that morning during his jog near the bench where the binoculars were left. Suleiman's only connection to the situation is his conversation with Yael in which they discussed the found item, and his assumption is based on this interaction without knowing the owner of the binoculars.

Yael, having found the binoculars and conversed with Suleiman, is aware that someone left the binoculars at the park and that Suleiman had seen but had not collected them earlier. She does not know that Kavi is the owner of the binoculars or that they were specifically left there by him. Her decision to leave the binoculars on Kavi's porch is borne out of the assumption that they might belong to him given his interest in birdwatching, a fact she knows comes from general neighborly interactions.

None of the three are fully aware of the complete sequence of events--Kavi's leaving of the binoculars, Suleiman's passing by without recognizing them, and Yael's eventual collection and return. Each person has a partial understanding based on their individual experiences and limited interactions with one another concerning this incident. Kavi does not know who returned the binoculars or if Suleiman or Yael know they belong to him, Suleiman doesn't know Kavi is the owner and Yael still doesn't know for sure if the binoculars belong to Kavi, only that she has attempted to return them to whom she assumes is the rightful owner.
