Caution: Pre-Teen Ahead II

How the hell do I gauge when a behavior is due to the Autism and when it is due to being 10 years old? Both can be difficult. Am I worried over something that, in the end, is pretty darned typical? Example: Isaac is being quite negative. He is under the impression that his parents are being unfair, and that we "hate" him. That we are not listening to him, and we don't understand what he is trying to say. Yes, he has used these words. I'm torn between taking his concerns seriously and being jazzed that he can communicate these feeling to us so well. Not to bad for a kid giving a Dx of moderate to severe autism when he was 4 yo. My perspective is rather tangled, I know. For now, I guess all I can do is take him seriously and not giggle and smile when I hear I'm go on like this. Good times.
