there are 3 kinds of acting.
White, Black and Rainbow.
but all in all, with 1 purpose, to act like someone who you are not.
so, when you grown up, you can't keep your innocence in the realistic world. you learn how to hide the real you. acting, is just one way to hide yourself.
its not like exercising your mouth, open and close, to say sorry. it takes courage.
and its not as simple as it is.
