I am surprised that no women have commented that this song is about murder. The guy is jealous. He beleives that if he doesn't own the woman she should be dead. There could be an innocent explanation. Perhaps he imagined the shadows of love. Perhaps the other man was a relative - e.g. brother, son. Perhaps she was smiling, not laughing, because she was glad to see him. But he didn't give her a chance to explain. He just knifed her.
