Are your Parents Aspergery?
From what I remember of my mother (shed died in 1975 when I was 10 1/2), there seem to be some hoarding traits, some definite skill areas and a 'quirky' sense of humour. She was also incredibly strict and although she doubtless 'loved' us (I can say that rationally, even if I don't 'feel' it), she rarely showed us any affection. She was also fairly socially isolated and was not the one who did all the housework and the 'taking care of things' on a day-to-day basis. She could get very stressed very easily - as can I now - and she was also incredibly strict in her treatment of us, for even the tiniest infraction. Also, if there was something on Television that she wanted to watch (she followed certain shows and soaps rigorously and if she missed them, there would be repercussions), then absolute silence had to prevail. I am a bit like that now, but living on my own, this is not a problem.
My step father (who is irrelevant in this), would mutter and talk to himself, a habit that I have been known to take part in from time to time.
I wouldn't say either were non-NT as there simply is insufficient data to work with, even though I think there are points of correspondence to the formal criteria.
