You are expected to be independent, but you remain dependent on your parents, your guardian ad litem or your guardian until you turn 18. As a young adult, there are many things you have to manage. You have to take care of your finances, study or work, wash, clean, cook and be in contact with government agencies.
These are things that you practice while living with your parents, in a HVB home or a foster home. Some things you will learn at school, while you have to find others out for yourself.
