Are any facial expressions or gestures considered rude?

* Rolling one's eyes when someone is acting out or making a statement. * Using your finger to make a circle on the side of your head that the person is crazy. * Mimicking the person that is saying something. * Flipping the middle finger (stuff it!) * Stifling laughter when the person is serious. No matter how funny one may think it is they should contain themselves because it obviously isn't funny to the person talking. * Making signals like behind the person's back (as above) that what they have to say is a crazy notion; mimicking them while scrunching up one's face of flipping them the middle finger. * Making faces on purpose for any reason is rude. * making really mean faces at someone is RUDE!!!!!!!!!
