A sheikh in our apartment building in suburban Melbourne gives Koran classes to children, and a few of the women who bring their kids here for lessons wear niqab. After passing each other coming and going a few times, we started to exchange brief greetings and introductions (yes, it's possible to recognise them despite the face veil, even on occasions when they don’t have the children in tow to serve as an identifier). The kids' response to these exchanges -- equal parts surprise and delight -- indicates that they have probably come to expect hostility from strangers on the street.
