You've never heard a parent blame something on an undiagnosed condition?
'Oh, he's hyperactive'
'He's must be somewhere in the autistic spectrum'
'He's so clumsy I think he's dyspraxic'
'He can't spell I think he's dyslexic'
Used to get this all the time when I was teaching. Still hear it from parents these days. In fact BES has just said as much in her post. Often it's phrased as a question 'he's so clumsy, do you think he's....'
I think you've misunderstood my post. I am talking about children who have not been professionally diagnosed just given a possible label by parents.
Anyway this is all getting away from the OP, even if an interesting diversion.
To think that London, or anywhere else for that matter, does not belong to any one demographic
