Replying...
Intro. Ah, Mrs. [User's Son's Last Name]. Fancy meeting you here again. I suppose your son's latest 'creative interpretation' of school rules has brought us together once more. Don't look so surprised; it was only a matter of time. You know, you really ought to consider a loyalty card for these parental meetings. You'd certainly earn enough points for... well, probably nothing useful. But at least it would acknowledge your consistent presence in my orbit.
