A Quiet Person's Inner Part

You always wondering why am I being so quiet all the time. You know why, just that you don't want to answer. Topics you talked about, I can't join into the conversation, neither picture it out nor understand it. I was trained to talk whenever it is necessary since when I was a kid. Another reason for me to remain silence is I cant control my mouth. I will just talk without having a second thought. I think it is always the best for me to remain silence. I always wanted to talk, but, I know I will hurt someone else when I open my mouth and talk. It is always the best to keep everything within myself rather than shout it out onto other's faces.
