Adulthood

It is more complicated life when you are an adult. Wait. But when you are considered as an adult? When does that start? So many things are complicated, we cannot act like when we are in elementary school. But I noticed, the older you get, the more acting like child people are. Don't you think? Maybe because when you are little, you always have "Parents/Parent" to tell you what not to do and what to do. After certain age, you are on your own. You just have to figure out what is okay to do or not. Of course bottom line is "don't break the laws" but besides that, there are so many thing you mustn't do, like hurt some one's feelings and so on. To me, this adulthood is too much. Actually life is simple , people are making it complicated. Why people cannot live simple ?When I said this to my friend, he told me "that is really Buddhist thinking" Is it? Is this Religious thinking or just true? I don't know.
