You now have to pay the bills, pay your rent, buy your own food, buy your own clothes, and pay for anything else that you could possibly want. But of course, with freedom comes responsibilities, and you can never run away from your responsibilities especially now that you're all alone in deciding what you want to do in life. The pros would be that you can do anything you want - sleep late, eat whatever you want, drink alcohol, smoke cigarettes, and of course, have sex with anyone and everyone that you want. There are pros, as well as cons that will come your way once you have complete and total control over your own life. It's at this age that people get to experience the world for how it truly is. These are the perfect words to use to describe someone who just turned 18.
