Yes, hilarious indeed! Yet it’s your face, so you really can turn your RBF off (or on) when you wish. All it takes is a mirror and some practice. It will actually hurt a bit at first if you do it too long or too hard. But that’s only your facial muscles getting a news exercise routine. (Just don’t go overboard with a manic grimace.)
This is not to reinforce anyone’s patriarchal demand for prettiness. Just to help you have control, and therefore a choice in how you appear to others.
