I want to be mature .I do not want my parents to worry about me .I want to be Independent. Let's my parent know I have grow up. I can do everything by... myself,and I am not a child any more.

Do you want to do some mature, don't want to parents coquetry, oneself learn to independence, let parents know that you have not a child.

You need to do some mature, not to the parents coquetry, yourself to be independent, to let them know you're not a child anymore
