Tell me that is probably just that he is "so bright, he just can't relate to other children!" That is a) not true, and b) NOT A GOOD THING
Tell me that you know someone who had that, and "THEY managed to work in a garden center!" - I have no problem with the idea of either of my children working in a garden center, but I don't want to think, at the age of 4, that that should be the sum total of his life's ambition.
"reassure me" - by telling me that I am wrong, he is totally normal, your child also displays many of the same behaviors and You are not worried, and that he will grow out of it all!
a) He is (very sadly) CLEARLY not NT. b), your child DOESN'T display the same behaviors - or you would be tearing your hair out too, which means that it ISN'T TRUE that you can cope with those behaviors and I can't. c) he is actually getting worse, not growing out of it.
ALSO do you not understand that by dismissing my concerns you make me feel worse and like I have to justify how bad my Darling DS actually is.
Finally PLEASE let me be sad, for a little while, that my son is going to have a much harder life because of how his brain works - without saying things like "he is still your little boy!" I KNOW THAT, AND I LOVE HIM AS MUCH AS EVER, BUT I AM SAD BECAUSE HE WILL HAVE A MUCH HARDER LIFE BECAUSE OF HOW HIS BRAIN WORKS.
Rant over, hope I haven't offended anyone, please feel free to add any of your own.
