I thought that once the parents of an older teenager determined that their child had learned all of the skills required to be an adult, they would tell their son or daughter, "Now you are on your own." On that day, the child would become an adult and no longer had to live with their parents or obey them. I think this belief came from a commercial where a father and son were roping calves and the father sent the son out "on his own" to do the job by himself.
