I wish certain people in my company would know that being nice and polite does not mean I am inferior to you. It means I respect you. I am not obligated to be nice to you. I do that because we are colleagues and I am genuinely nice. If you are taking this for granted, I will show you the side where you do not even deserve my respect... where there is not a single ounce of niceness or politeness... where I treat you as an object.
Think before you act.
