Non Verbal Communication

People have different kinds of signs to show how they feel and how they act.
_ Sometimes when I talk to my dad and he doesn't like the way I talk to him or he doesn't like the idea that I told him he shakes his head three or four times and that mean that he isn't agree about what I am saying or he didn't like the idea that I am tellling him .
_ The same thing with my mom, when I talk to her about something and she doesn't like it, she just turn her head to other way. That's mean she isn't agree with me.
_ Sometimes when I talk to my sister in the mean way her face turns to red and her eyes too so that mean that she mad at me.
