they also have a pathological hatred of telling people what they've 'done'
this I put down to them
a: not actually knowing what they've done
b: not wanting to let on to 'lesser mortals' that they don't really know what they've done
c: paranoia that they will get found out that they don't really know what they are doing
d: even greater paranoia that one day they may have to deal with someone who actually
does understand whats going on, and that that person will suddenly realise points a, b and c.
This makes them very afraid and reminds them of the fact they wet the bed till they were 17 and couldn't get a proper job
