So imagine you're at a playground with all your friends. You're all having a great time playing and having fun. But sometimes accidents happen on the playground, right? Like if you accidentally bump into someone and they fall down.
Now, let's say you accidentally cause someone to get hurt. You didn't mean to, but it happened. That's where nezikin comes in. It's a set of rules in Jewish law that talks about how to take responsibility for those accidents and make things right.
For example, if you accidentally broke someone's toy, you would need to pay for a new one to replace it. Or if you accidentally hurt someone, you would need to apologize and make sure they get the help they need to feel better.
It's all about being responsible for your actions and doing what you can to make things right when something goes wrong.
