I find it confusing when people say they are sorry about things like that. Its not necessary a bad thing because its just part of who they are. Like if you had a child with ginger hair, you'd be a bit offended if people said they were sorry because its normal to you
Most conditions like dispraxia, dyslexia, and things like autism and downs syndrome are suggested to have high intelligence.
The problem is that most of the time people under appreciate this because they see a child looking or behaving in a certain way and presume that theres a lack of intelligence.
