And this whole house has been damaged but then if you look at the sociological and psychological aspects why these houses are located here, on the top of the ridge or the top of a in a slightly higher area, it’s not a mountain area but slightly but if you ever looked from the rich houses villages, you will see the whole entire village.
Detailed Explanation
This chunk discusses the significance of housing locations in terms of societal structure and status. Houses situated on higher ground often belonged to wealthier individuals, indicating their social standing and allowing them a commanding view of the surrounding area. This arrangement reflects historical societal structures where the rich and powerful lived separately from lower socioeconomic classes.
Examples & Analogies
Think of how castles were built on hills in medieval times. The lord and his family lived there, able to overlook their lands and the village below, symbolizing their power and control over the lower classes who lived in the valley.

So, that is where this unsafe houses has become a shelter for the corridor between these two families has become a shelter for the homeless people, but the question is, is it really safe to live there? Because aftershocks might keep coming on and there might be a possibility that you can see that whole damage has been occurred.
Detailed Explanation
This section raises concerns regarding safety in makeshift shelters constructed after damaging events like earthquakes. While these structures might provide immediate refuge for displaced families, they often lack the necessary stability and infrastructure, making them potentially unsafe in case of aftershocks.
Examples & Analogies
Imagine placing a tent on a shaky platform. While it may offer temporary shelter, it could easily collapse if the wind picks up or if the ground shifts beneath it, similar to how unsafe makeshift homes can pose risks during aftershocks.

But you look at it the wealthy class of the village, they have a detached toilet system and detached washing systems towards the rear side so which means though the independent families are segregated by wall and the common corridors at the end like you have the 3 families living like this but they have a common toilet.
Detailed Explanation
This segment highlights the disparity between living conditions for different socioeconomic classes. Wealthier families often have separate sanitary facilities, indicating their higher living standards, while poorer families may share common facilities, which can lead to hygiene issues.
Examples & Analogies
Think of an apartment building where the rich residents have their own private bathrooms, while tenants in lower-income units must share a bathroom down the hall. This setup can lead to cleanliness problems and social tension between the groups.

So, that is where the schools have been stopped for about one year, nearly one year. So, how about education, you know what to do, how we can engage the community and the children because you know that is also needed.
Detailed Explanation
Following a disaster, many schools may be forced to close due to damages, disrupting children's education for extended periods. This leaves communities in a difficult position as they search for ways to provide educational opportunities and support for affected children.
Examples & Analogies
Consider a town that suffers a flood, leading to school closures. Children are left without classrooms, and their learning is interrupted. The community must come together to find temporary solutions like setting up classes in local shelters or outdoor spaces.
