I just get pissed off when people have utterly unrealistic expectations of a teacher.
You don;t know why this guy wasn't there.
He could have been in an accident.
He could have become ill overnight.
He could have had an in visable condition that got worse overnight.
Someone in his family could have been ill, or died.
He would even have been sent on a very ill times training course.
He could of course, be swinging the lead.
But it irritates when a parents immediate response is to whinge, when they don't know the facts.
Post tomorrow that you saw him painting the town red tonight with no problems, and I'll sympathise. If not you are being unreasonable and rather irriating.
Everyone has a the right to be an arse on MN. Trying to justify it is rather more problematical
