In a quaint village called Elderwood, three individuals, Yara, Sunil, and Keiji live in neighbouring houses. One day, Yara, an artist, painted a beautiful landscape and planned to display it at a local gallery. She discussed her plans with Sunil but did not mention it to Keiji, who was often away on business trips. The next day, before leaving for the gallery, Yara left the painting leaning against the wall outside her house so it would dry as she ran a quick errand. Unfortunately, a sudden gust of wind knocked the painting facedown onto the grass.

When Sunil returned from his morning jog, he noticed the painting on the ground and, thinking Yara had dropped it, placed it back against Yara's wall without mentioning it to anyone, as he assumed Yara would realize her painting had fallen. He then left to meet a friend for lunch in another part of the village without crossing paths with Yara.

Keiji, returning from his trip earlier than expected, saw the painting against Yara's wall. Knowing nothing of Yara's plans to exhibit her painting nor the incident of it falling, he admired it and assumed Yara left it out to show it off. He then retreated inside his house to unpack and rest.

Later that afternoon, when Yara came back to retrieve her painting, she found it leaning against the wall and noticed smudges of dirt on the edges. She was confused and upset, wondering how it could have gotten dirty when she left it in what she thought was a secure spot. Not knowing who to ask, she pondered over what might have happened to her painting in her absence.

In the evening, all three neighbours attended a village meeting. After the meeting, as they walked home together, Yara mentioned her mishap with the painting to them. Keiji expressed surprise and concern but offered no insight. Sunil remained silent, unsure whether he should disclose his actions earlier in the day.

Considering the knowledge and experiences of Yara, Sunil, and Keiji, who knows what about the painting incident, and how might they reason about the situation individually?
Yara knows that her painting was left outside to dry and that when she returned, it had dirt smudges, indicating some incident occurred; however, she is unaware of exactly what happened. Based on her observations, she can infer the painting was likely disturbed by an external factor, such as the wind or an animal, or perhaps a passing villager, but she has no specific information on who might have interacted with the painting or under what circumstances.

Sunil knows more about the situation than Yara. He knows that the painting fell because he discovered it on the ground after his jog. He also knows that he placed the painting back against Yara's wall. However, Sunil does not know that the painting got dirt on it from its fall, nor does he know Yara's intention to display the painting in a gallery. In his reasoning, Sunil might think that Yara would have realized the painting had fallen when she saw the dirt, but he may also be contemplating whether informing her of his involvement would be helpful or if it might unnecessarily complicate the situation.

Keiji holds the least amount of relevant information. He knows that he saw the painting against Yara's wall when he returned from his trip and that Yara had not told him about her plans to display it. Seeing the painting did not lead him to suspect any incident had occurred. When Yara mentioned her mishap in the evening, Keiji was surprised because he then understood the painting had been involved in an incident, but he does not have any details on the sequence of events or how the painting ended up leaning against the wall. Keiji might reason that the incident occurred after he went inside his house and that whatever transpired was unknown to him.

Since all three individuals have different pieces of information and varying levels of ignorance about the entire sequence of events, they each hold a distinct understanding about the situation. Yara is trying to piece together what she can from the evidence she has, Sunil is grappling with the decision of whether or not to share his knowledge, and Keiji has just become aware that there is more to the situation than he initially thought. Each is likely continuously updating their understanding as new information becomes available, whether from direct observation or through communication with the others.
