Behavior is how we act and respond to things around us. It can be anything from how we talk, to how we move, to how we act in different situations. We develop most of our behavior as we grow up, as we learn more about the world. Every person behaves differently, and it can depend on their personality and their past experiences. Parents often work to teach their children appropriate behavior, like using good manners and being respectful to others. Good behavior can have benefits like making friends and being rewarded. Bad behavior can have consequences like getting in trouble or being excluded.
