【明報專訊】When someone comes to Hong Kong from another country, one of the first things you notice is that on the bus and on the MTR, people often will not sit next to you! This is quite a shock when you first experience it, and takes a while to get used to. Recently I met a lady from Africa who has been in Hong Kong since the start of this year. She cried when she said how it hurts her that rarely does anyone sit next to her on a bus or on the MTR.
