Okay kiddo, so you know how sometimes we need help from adults when things get all confusing and difficult? Like when you need help with your homework or when you get hurt and need a doctor? Well, adults sometimes need help from other adults too, and that's where lawyers come in.
Lawyers are grown-ups who have studied a lot about rules and how to keep people safe and fair. They help other grown-ups understand these rules and use them to solve problems. For example, if somebody gets in trouble with the law or if they want to make a big decision like buying a house or getting married, they might need a lawyer to give them advice and help them with paperwork.
Now, being a lawyer is not easy. It takes many years of studying and training to become one, and you have to be really smart and good at solving problems. When a person becomes a lawyer, they have to follow special rules and promise to always be honest and fair in their work. This is called the "practice of law".
Basically, the practice of law means that lawyers have to use their knowledge and skills to help people in a fair and honest way. They have to follow the rules and do what's best for their clients, but they also have to follow the law and make sure everyone is safe and treated equally. It's a big responsibility, but it's also really important because it helps people get the help they need when they need it.
