GENTLE READER: A lost art, which especially needs to be revived in just such situations, is Pretending Not to Notice. It is true that one should try to be what is called “presentable,” whatever that means in a particular context. However, it is incumbent on passersby to pretend not to notice. If someone has a pimple on their nose, or any other physical irregularity, those who are not intimately involved must pretend not to notice. Listen to the music and pretend you do not notice the background.
