I'm often a wrong aspie, as are lots of other aspies I know. We don't like being wrong but we're well used to it. We know how hard it can be when someone points out our faults and explains how we got it wrong all over again. It means we become awkward under criticism - obnoxious at our worst.
So it's ironic that an aspie in the right is such a big pain in the butt. (Yes, you are, you know it). If being wrong is painful to the aspie, then being right is at least as big a pain to everyone else.
It's not so much gloating (though some do like to gloat); rather it's to do with:
Making sure the person realises they are wrong, understands how they are wrong and can show the aspie they know they are wrong otherwise there will be absolutely no shutting up about it.
It's almost helpful, this need to point out your wrongness. If we tell you how you went wrong and the many vivid details of your errors, then you'll know not to do it again. We don't like to be wrong and always try to avoid it so we don't mind repaying the favour and helping others avoid wrongness too. It's a public service.
If you do something the wrong way and we know the right way then we will tell you the right way. And when good manners or social shock cause you to clam up and just let us go on, we will take that as your misunderstanding of what we are trying to explain and so we'll continue explaining. And there will be hand gestures and show-and-tells and detailed explanations with figure diagrams and also references to your wholly wrong effort, so you know where you went wrong.
None of this will be meant unkindly but there will be a firmness about it, as if you are 5 again and having it explained to you why it's a bad idea to talk and eat at the same time. You will be left in no doubt as to how you went wrong and that you are being Put Right.
At the end you have the choice to accept the staunch advice from your helpful aspie or venture a small complaint about the method of correction. This would be the moment when you try to explain how the aspie made the lecture kind of painful and did they know they had hurt your feelings?
If you manage to finish the sentence, your aspie will be dumbfounded, appalled, just totally brimming with disbelief - not at having hurt your feelings but at your ability to sidestep the whole point of this exchange and move onto your emotions (again!). All the effort put into explaining how you went wrong seems to have been wasted. How is your aspie expected to help you if all you do is lose concentration? No wonder you get things wrong!
The suggestion that the way your aspie explains things might be slightly abrasive or hurtful is irrelevant. As usual, if it wasn't meant this way then there's no point in you taking it this way. If you can't use good advice when it's offered, your aspie might have to stop offering it (no, there's no real hope of this happening, sorry).
Sadly, your aspie wanders off, secretly plotting how to help you be right once you've stopped being silly and are ready to listen. Or maybe you can just be shown the right way to do something? Be converted by the brilliance of the finished effort?
Smiling to themselves, your aspie closes the door, leaving you to wonder what on earth you did to deserve a ten minute lecture on the right way to clean a sink. Especially as you're the only one who ever does it!
Sighing, you take up the cloth and then hesitate, looking guiltily at the kitchen door as you start to clean the sink the way you were told. Sometimes it's better just to do things right...
