Okay kiddo, imagine you have this special container that holds lots of different things. Let's call it a gostak. Now, the gostak has different compartments where you can put different things, like toys, crayons, and snacks.
Now, imagine that you have a friend who also has a gostak, but their gostak is a little bit different than yours. Maybe their compartments are arranged in a different order, or maybe their gostak is a different color.
So, when you and your friend want to share some things, you have to figure out how to put the right things in the right compartments. If you put a toy in the wrong compartment, it might be hard for your friend to find it later.
In a way, gostak is like a language that helps you and your friend talk about your gostaks and share things. You might say, "Put the blue toy in the second compartment from the top," and your friend will know exactly where to look.
That's basically what gostak is all about: using special words and phrases to talk about things in your gostak and share them with your friends. It might seem a little tricky at first, but with practice, you'll be a gostak expert in no time!
