Did you have an aunt when you were small? Or a neighbor? Someone who showed or told you completely different things than your parents did? Someone who comforted you? Someone who listened when you had questions? Someone who helped you when you had problems?
Children learn from their parents. Parents can't know everything. That's why it's important to learn from other people too. KulturPatinnen/KulturPaten (cultural mentors) help with this. They answer questions. They talk about their everyday lives. They can help with many things.
