We are always together. I never noticed him doing what you just said. Keep your perceptions to yourself. They won't satisfy me. So what if he drinks or smokes? He does that in front of his father. When they are cool with it why are you bothered? Also, you need not tell me whom to trust I know very well. I appreciate your concern towards me.
But don't just speak until and unless you aren't sure about anything. I won't answer any questions regarding him.
