Despite the fact that before he became Sting plain old Gordon Sumner was an english teacher, this song is apparently a work of complete fantasy (a claim which is probably borne out by the fact that none of the pupils he taught has ever claimed to have had an affair with him). As quoted in Q Magazine in 1993:

"I was a teacher but I never had a relationship with any of my pupils, I wouldn't want to. You have to remember we were blond bombshells at the time [the track was released] and most of our fans were young girls so I started role playing a bit. Let's exploit that. And it really worked. You know that single sold a million copies in Britain. A million. Imagine that now?"
