He's told me that:
- he won't sit with anyone, even at lunch, even if asked
- he orders everything (pens, post-its etc.)
- any messages taken have to be written in full prose, with different coloured pens for different parts of the message. NO PART of the message must be missed - literally a word-for-word transcript.
- he nods constantly when being spoken to or listening to radio/on the phone or whatever
There are a bunch of other things too (like, doesn't wear appropriate clothing for work, cannot co-ordinate outfits etc.) but I didn't think these were so relevant. He could just be a bad dresser
