It is hard with the making excuses thing. I would accept behavior out of the ordinary from a child who was autistic on the ground that they are well autistic. I would not expect a child in a wheelchair to win a running race, I would accept that a child with an IQ of 70 may need extra help, etc. Why is it strange that a HG child may need extra help to thrive at school and may be unhappy and/or disruptive if they don't get it.
