Okay kiddo, imagine you have two friends who each have different rules about playing tag. Friend A says you can't touch the other person below their waist, while Friend B says it's okay to touch anywhere.
Now imagine you're playing with both of your friends at the same time. You tag your other friend below their waist, but Friend A gets upset and says you broke their rule. Friend B is confused and says that they never heard of that rule before.
This is kind of like a conflict of contract laws. It happens when different places have different rules for the same thing and they can't agree on which rules to follow.
But instead of playing tag, it's more serious things like when companies or people make agreements (called "contracts") with each other. Each place has its own set of rules (called "laws") and when two parties from different places make a contract, they have to decide which laws they will follow.
This can be tricky because some laws might conflict with each other. For example, one place might have a law that says a contract is only valid if it's written down, while another place might say that verbal agreements are also valid. If the two parties making the contract can't agree on which laws to follow, it could cause a big problem and they might need a judge to decide which laws should be followed.
So, just like when you play tag with friends who have different rules, it's important for people making contracts to talk about which laws they want to follow and make sure everyone is on the same page.
