Your brother is scared to go to the dentist. Your mum is taking him but pretending that she is taking him to the swimming baths. She tells you not to tell him the truth. Is this a good secret or a bad one?

A secret is something only you, or you and a few other people, know. Some secrets are good – like when you are arranging a surprise party, or if you have bought somebody a present and don’t want them to know what it is.

Some secrets are not good. When people try to hide things that are wrong, or things that could be dangerous. If you are ever asked to keep a “bad” secret then make sure you tell either your teacher or your parents.
