David, excellent point. Being adult is not chronological in nature. As an instructor you are just as likely to encounter 35 year old adolescents as you are 25 year old adults. What is important is to have dialog with your students, get to know them and where they are on the maturity scale. Those that are less mature may require more of your time and some tough love when it comes to guiding them to a higher level of understanding of themselves and what will be expected of them in their career field.
