Okay kiddo, so you know how sometimes when we do something wrong, we have to go to court and the judge decides if we're guilty or not?
Well, sometimes people don't want to say they're guilty, but they don't want to say they're not guilty either. So, they say something special called "nolo contendere" which means "I do not wish to contest" in fancy lawyer language.
It's kind of like not saying anything at all, but it means you won't argue or fight against what the judge says. So, the judge can still decide what happens to the person, but they didn't technically say they did something wrong.
It's like if you didn't clean your room when I told you to, but you don't want to say you did anything wrong. So you tell me "nolo contendere" and it means you won't argue with me about it, but you don't admit to doing anything wrong either.
Does that help, sweetie?
