To become an adult that means you have to take full responsibilty for your actions, and also to make responsible actions. Many people are not ready for the adult world, because they are not ready for being responsible for themselves. Being an adult doesn't simply mean being 18. People who are well over 18 , still are not adults. To me, being an adult is more of a mental thing than just physical. Becoming an adult means growing up, and being responsible. My mom teaches me how to be an adult just by doing little things. Ever since I was younger I had chores to do, and I was responsible for remember to do them when I got home or I couldn't do other things that were more fun that I wanted to do. Since I was a child I feel as though I was always ready for the adult word, because my mother has done all she could to prepare me.
