I need to apologise.
Apparently the teacher didn't say 'Asperger's', but said " Anyone who has a physical or mental disability or illness." John knows that here AS is considered to be a disability, therefore felt that this comment included him, although it wasn't aimed at him.

I'm not certain if this is better or worse than the original version I received.

to MadKangaroo, of course teachers just like anyone else make mistakes, but  like anyone else are held accountable for their actions. In the UK,they receive much better pay & conditions than  nurses.

To  bwcagirlmn, yes all of the teachers in the high school are aware of John's AS, this is common practice here so that teachers should be aware of potential problems ie the usual for AS's....communication, taking things literally etc.

To violet_yoshi, some years ago, when John was around 9, we visited an exhibition of the emergency services.
we visited the Firemens tent, the fireman asked all of the children what would they do if there was a fire in their house at 2.am.
Most of the children answered as they had been taught, ..."crawl on the floor, put a wet blanket on me" etc.
The fireman said "Wrong , you would be asleep so you would die !!"

Can't argue with that because he was correct, but John was afraid to go to sleep for years.
