Since everyone became an adult. Consider it one of those untaught lessons about growing up. You should have one, or at least, know how to access one, just like doing your taxes, either with a CPA or by hand, or like going to the dentist. Your life may have taken a different route, and you've not come across the need for one, but it's like getting married or having children. As an actualized adult, you should be aware that lawyers exist in more than a passing fashion or what you saw on Law and Order.
