So, let's say you have a big toy box full of toys. But one day, Mom or Dad tells you that you can't play with any of your toys from the toy box. They put a big lock on the toy box and they won't give you the key.
That's kind of like what's happening with the West Bank closures. The West Bank is a place where a bunch of people live, and there are stores and schools and things like that. But sometimes, the people who control the area (like the police or the military) decide that nobody can go in or out of the West Bank.
So it's like they're putting a big lock on the West Bank, just like the lock on your toy box. Nobody can go in or out, and that means that people who live there might not be able to go to work or school, or get the things they need from stores.
And just like you might feel sad or frustrated if you can't play with your toys, the people who live in the West Bank might feel upset and anxious because they can't do the things they need or want to do.
