After heavy rain, I started paying attention to how water behaves around buildings instead of just assuming everything is fine once it dries up.
One thing I noticed is that water doesn’t always drain evenly. In some areas it flows away quickly, but in others it tends to leave behind wet outlines or darker soil patches before fully drying. I saw a situation where one side of a compound always stayed slightly damp longer than the rest after rain. At first it didn’t seem important because it always dried eventually, but over time the difference became more noticeable. Even the soil in that area started to look slightly different in texture compared to surrounding areas. Not something you notice immediately, but once you do, it’s hard to ignore.
I think what people miss is that water always shows you weak points in the environment. It settles where it finds the easiest path or where drainage isn’t as strong.
Now when it rains, I sometimes just observe instead of ignoring it. It tells you more than you expect if you actually pay attention.
