DD is 12 and this man is one of the English teachers. Everyone loves him. He is well known at the school for having an interest in film and running the film club. It is a widely held belief among the older girls that he directed a number of porn films. There is a director with his name and appropriate looking dates listed on the IMDB website with credits of dodgy looking movies. Private Anglican girls school.
If this is true and it is indeed him, WIBU to raise it with the principal? Or, as my DC insist, is it not relevant to his teaching ability? There is no whisper of anything untoward in his behaviour at school.
