The next thing you would do is walk straight into an operation theater during an operation and ask all the doctors and nurses to remove the masks from their faces because it is rude to talk like that because during the operation the docs must have a face to face conversation.
Then you would also try to teach manners of taking face to face to people in public who are trying to avoid dust and pollution.
Then you would walk into industries and remove the masks of the workers because they are working together but are being very rude to each others because they are not talking face to face.
The last thing I would hope for you is that you may never walk into a room where doctors are trying to supply oxygen to a rude patient through something that is preventing a fact to face talk..
