Well hello there, kid! Do you like maps? Quasi-open maps are like a special type of map that helps us see where things are.
Think of it like this - when you go on a treasure hunt, you need a map to find where the treasure is hidden. But sometimes, there might be some parts on the map where you're not sure if you can go through or not. That's where quasi-open maps come in!
These maps show you where you can go through and where you can't, but they also help you figure out some tricky parts where it might be a little bit hard to tell. It's kind of like a dotted line on a regular map - it shows you a path, but not exactly a whole line that you can follow without fail!
So, a quasi-open map is like a special kind of map that helps us find things, but it's also there to guide us and show us what the best way is to get where we want to go. Pretty cool, huh?
