Growing up is something everyone goes through. It’s when kids turn into teenagers and then into adults. During this time, people learn new things, try different activities, and begin to understand the world better. It’s not always easy. Sometimes it’s fun, and sometimes it’s confusing. That’s why people use idioms fun phrases that help describe what growing up feels like.
