Alternating offers protocol

Let's say you and your friend are playing with a toy together, but you both want to play with it in different ways. You want to build a tower, and your friend wants to make a castle. You both have to negotiate and decide how to play with the toy.

An alternating offers protocol is kind of like that negotiation process between you and your friend. It's a way for two people to make a deal or come to an agreement when they want different things.

Here's how it works:

- You and your friend take turns making offers.
- You say what you want (to build a tower), and your friend says what they want (to make a castle).
- If the offers are different, you start negotiating. You might say, "Okay, how about we take turns building and see what it looks like?" Your friend might say, "Sure, but I get to add the flags on top!"
- If you can't come to an agreement, you keep making offers until one of you gives in or you agree on something.

This might sound complicated, but it's actually a good way to make sure that everyone gets a chance to say what they want in a negotiation. It also helps prevent arguments and helps you work together to find a solution that makes both of you happy.
