My mum and I both find we have a hard time understanding what a person says if we don't look into a person eyes, we can hear the words,, but we don't know where to put them in our brain, it's almost like being thought deaf for us.
We've both been accused of trying to see right through to a persons soul, that we're too intense in our focus.
But my dad says if you stare at someone for more than 8 seconds it's considered rude or agressive, but the thing is, I've found if someone looks at me first I have to stare at them until they blink or look away, which ended with me being bullied at secondary school.
We both connected really strongly to a line in Law and Order; Criminal Intent, where a man with AS said that if he stared for a certain length of time he was considered agressive, but if he didn't stare at a person for long enoguh he was considered dishonest.
So it's seems like there's no real answer for those with AS, plenty for those who are NT, I'd love to know the rule book they all got handed at birth, but then if I ever got a chance to borrow it, it would probably not make that much sense, so like I said: No real answers!
