Some of the responses above make me realise why my ex-girlfriend - a teacher - often left school in despair sometimes at the audacity of some parents who took it upon themselves to declare their moral predilections in defence of their own cherub. Often physically, often verbally, but ultimately psychologically.
The teacher is exercising his duty to you, the school and your son�s education and upbringing which is obviously of concern to them, if not you. And all you are worried about is his personal affairs? You probably know nothing of his life, but I am certain he will know all about you and yours.
Its pitiable.
