What is the best way to treat meddlesome people?

The best way to treat meddlesome people is either to ignore them or tell them their mistakes. Both of them are good ways, but I prefer to tell them their mistakes. Only for some cases, you try to ignore them. If you do the way I like, the meddlesome people will know thier mistakes and MAYBE change into a new leaf. They will also learn from their mistakes. If the meddlesome people still is not willing to change and matters gets worse, tell the teacher. That is how I teat meddlesome people. That is the end of my entry.
