Today I was Thinking

Today in class I had started off by writing my journal. My journal was based off how the words we choose make an impression of who we are. Your personality can define who we are and our personal traits. I started to think why people act the way the do such in a good way or a bad way. From my point of view it seems that some people would act differently to make someone think who they are. Do you think that most people are defined by their vocabulary of speaking?
