Find out what mrs Brown is telling her son.Use will ('ll) or won't. Помогите!!!

One day you will be a parent. You will have children. They will think you're old. They won't listen to you. They won't like the things you like. They will laugh at you. And you won't like it. You won't! You won't understand it! You will think they're too young. You will think you're right. It will be the same thing. So, please do what I say.
