Describe an event that made you realize you were frowing up/maturing. What happened? How old were you?

Well when I knew I was maturing was when I moved out of my parents house when I was 18. Before I moved out I had a job and saved up money and moved out. Then when I was moving I had to change everything into my name. I felt like an adult and I felt very mature. I had my own place and my own car.
