What is Leaky, dying ones?

Leaky and dying ones are special kinds of pretend doors that sometimes let things through or stop working completely.

Imagine you're in a big house full of rooms, and each room has a door made of glass. These doors can be leaky, like when the glass is foggy or broken, so instead of keeping everything inside nicely, some stuff slips out. That’s what leaky ones do: they let things escape when they shouldn’t.

Now, think about another kind of door that sometimes just stops working entirely. Maybe it gets stuck, or you can't open it no matter how hard you push, and once it stops working, it might never work again. These are the dying ones. They're like your favorite toy that suddenly breaks during playtime and won’t work anymore.

So, in a way, leaky ones are like doors with cracks, while dying ones are like doors that just give up and stop working completely. Both make things harder to keep inside the room, but in different ways!
