The idea here is really strong, well-told, and the twist at the end leaves the reader feeling like it was all worth it, which is always nice…

Some of your sentences are a bit messily structured, with lots of commas where you could probably afford to split it into several sentences – for example:

‘Then he realised, he knew why they were all staring at him, of course they were, if he was in their position he would be doing the same.’

Could read better as:

‘Then he realised, he knew why they were all staring at him. Of course they were – if he was in their position, he would be doing the same.’

It just reads better if you ask me – there are a couple of other bits where this kind of edit would be helpful as well – just look for excessive commas…

But as I said above, the plot, word choices and jokes in there were really good fun – well done! MH :)

Thanks, I did write this this morning while slightly hungover, and to be honest grammar is not my strong point. Thanks for reading and for rating. I appreciate it.

MH mentioned all the technical stuff I would have said. I really enjoyed this piece. I thought at the end he was going to be a student with no pants on or something, like in a bad dream. It was interesting to realize that the teachers might be nervous on the first day of school, too. Especially at the university level. Nicely done!

I agree with everything previously stated, but they failed to remind you, that although you may be a little out on characters, it is always a good idea to separate paragraphs. This was a bit jumbled and everything, but otherwise a good view in a teacher’s head.
