Foxy, it's very tragic, as you say.

One summer's afternoon some years ago my wife and I witnessed a young Chinese couple quarrelling in the street. No-one dared to intervene. We all looked on as the quarrel intensified. Finally, the young man produced a long knife and stabbed the girl to death with several thrusts of his knife. The police arrived shortly afterwards and detained the young man. Later, we heard that they were university students who had been lovers, and the girl had told him she was finishing with him because she was in love with another student. She was rather beautiful.
