Have you ever heard someone say "don't count your chickens before they hatch" or "actions speak louder than words"? These are examples of common sayings. People use these sayings to explain something in a very clear and easy way. It's like they have a message that they want to share, and they use the saying to share it with other people.
But where do these sayings come from? Well, just like stories, they have been passed down from generation to generation. Some of them have been around for hundreds of years! They were created by people who wanted to teach others a lesson or give them advice.
For example, the saying "don't count your chickens before they hatch" means that you shouldn't be too confident about something before it actually happens. It comes from the idea of a farmer who has a bunch of eggs that he hopes will hatch into baby chickens. But until they hatch, he shouldn't count on having any chickens at all.
So the next time you hear a common saying, think about where it might have come from! It could be a really old message that someone wanted to share with others, to help them understand something important.
