I watched the Judge Judy. Dislike the feeling that sometimes Judge Judy is above everyone, but do like the way that she solved the problem logically, quickly and clearly.
What I learned are firstly a lie is never going to stand; secondly, listen a question clearly; thirdly, answer a question to the point simply and sensibly; fourthly, US law and common sense. I think the first three points are suitable for communications and the life too.
Not sure if there is a similar programme in the UK, so people can learn British law through those cases and stories.
