Do you talk to your self?

Do you talk to your self? 
It’s OK …having a running dialogue with yourself, if you run the conversation silently in your heads, that is. That’s normal.  
Besides, how else can you justify your existence except with a constant dialogue with your self? 
There has to be a constant reassurance that there is a little man or woman, a self, a mind inside your brain which is the essential you. 
One should not worry about having an inner dialogue, it is quite normal.
