What are initial exchange between two entities?

An initial exchange is when two people or groups start sharing things with each other, like trading toys at a playground.

Imagine you and your friend are playing with blocks. You have red blocks, and your friend has blue blocks. You both want to try each other’s colors. So, you give each other one block. That first trade is your initial exchange, it's how you start sharing.

Now think about when you bring a snack to school, and your classmate brings juice. You might swap them. That first swap is also an initial exchange. It’s the beginning of a friendly trade, like how you start a game by passing the ball.

In bigger places, like stores or businesses, people do initial exchanges too, they trade money for things they want. Just like you trade your blocks for new ones!
