when i do not speak

I do not speak, does not mean I'm afraid;
I do not speak, does not mean I am angry;
I do not speak, does not mean I have to be bullied;
Me do not talk, does not mean recognition is my mistakes;
I'm just lazy and do not want to explain the silly questions;
there was been a long time , but now understand, is you do not find that, I have not to take you to be a joke or when the butt of jokes.
