This is a difficult question to answer it just a short paragraph; because, it really depends on the particular teenager. Some teens can be responsible, and obey their parents, while others can be extremely rebellious and do basically whatever they want, whenever they want. It really depends on the parents and the general attitude of the teenager.
Most teens are fairly responsible, but their minds are not yet fully developed. Therefore, although they are responsible, sometimes they don't remember everything or follow through with all of the responsibilities they are given. Although they should be trusted, unless they have given a person reason to believe they should not be trusted, they still need supervision.
