"Mister" is a polite way to address a man or boy, especially one you don't know well. You would use "mister" when you meet someone new, when you talk to a teacher, or when you visit a doctor. It's important to use "Mister" instead of just their first name because it shows respect and politeness. For example, instead of saying "Hey, John!" you would say "Hello, Mister John!"
