everyone likes to have a good time once and a while, but if you don't ever act your age people think your immature. They have trouble talking to you and cannot have a serious conversation with the person. One example of this is the way Robin Williams used to act, in his movies and in the real world. I would hate to be one of his kids, because you could never talk to the guy. He had a hard time being serious. I think in many ways people were annoyed by his behavior. In retrospect, the guy has improved and now is playing roles that are more serious in movies.In conclusion, I think it can be said that there are more limitations with growing up. You are expected to do more, and are given more responsibilities. You have to be a good role model. Most of all you are allowed to make mistakes just learn from them. Some 50-year-olds are less grown up than some 20-year-olds. Whatever your age though, does not let anyone force you to grow up. That is something you can do on your own....
