Please get a grip. I know you are tired, although God knows why as all you seem to do at the moment is sleep - particularly whilst I'm awake. There is only one more day of school to get through so please return from whatever corner of my skull you have chosen to hide yourself and get with the programme.
It is not helpful that you tell me all day that I have a choir rehearsal tonight when it is, in fact, tomorrow night. I can only be thankful that your absence is recent and you previously had the wherwithal to WRITE THINGS DOWN, because otherwise I would have looked a mighty fool at 8pm, standing around outside an empty building wondering 'Where is everybody?' like the giraffe on that old British Airways advert.
It is a point of fact, dearest Brain, that this absence is quite unacceptable. You are - unfortunately - quite indispensible and irreplaceable as I tend to need you in order to form coherent sentences and hopefully avoid that gut-clenching feeling of social inadequacy.
I know that hours upon hours of wrapping up brightly coloured pencils for the children in my class may well cause you to slip into a trance-like state of sheer, unadulterated boredom, but I'm afraid it can't be helped. There will be time to sleep next week, and to think about nothing more strenuous than what to have for lunch, but until then I must insist that you return to full functionality immediately.
So here's the deal, Brain, let's get through the next couple of days and then you can relax, maybe even take a holiday, on full pay of course. Just don't abandon me yet.
