Think about a straw you use to sip your juice. The straw is narrow because it is long and thin, letting only a small amount of juice through at a time. If it were wider, more juice would flow through it quickly. But because it’s narrow, it controls how much juice you drink in one sip.
Now, imagine a path in a forest. A narrow path is like a tiny trail where only one person can walk at a time. You have to be careful and walk in a line. If the path were wider, you and your friends could walk side by side. But because it’s narrow, you have to go one by one, like a line of ducks.
Think of a book with lots of pages. If you open it just a little bit, you see only a narrow part of the page. You can’t see the whole picture or all the words. You have to open it wide to see everything. But with the narrow view, you only get a small peek at what’s inside.
