The other day I was sat at my desk happily minding my own business when the vice principle shuffled in and smiled at me. He paused at my desk as if preparing to say something to me, thought better of it and turned to my coteacher.

I heard my name mentioned a few times and when I turned he did another suspicious smile at me. Then Grace, my coteacher, translated the message 'You must look pretty on Monday'. I was sat with unkempt hair, in an outfit I had thrown on in 2 minutes that morning, so wasn't quite sure how to take the comment, but I just smiled at him and he looked relieved and left.

So on Monday the pressure was on, not really knowing why I'd had to get up so early, I brushed my hair and put on a dress. When I got to school I was ushered into the library where there was lots of photo equipment set up, and three immaculate children who'd had almost a bucket of water thrown over their heads to smooth all the stray hairs down. Then I was told to stand on the desk.

Here's the result of the bizarre photoshoot. Apparently it's a poster to recruit new students for next year. It was pretty awful when I noticed that the poster was going up in every classroom, but I've just been told that each child in 4th, 5th and 6th grade has been given a poster to put up in public. Great.

So see how many you can spot over the next few months and try suppress the urge to deface my awful grimmace.
