I have disclosed the Asperger's to my wife's sister, and she has seen a glimpse of the "beast". I was having dinner with my wife, her sister and their aunt. In paying the bill my sister-in-law decided to review the gratuity/tip and proceeded to change the amount I was paying. That resulted in am unexpected mini-meltdown which I later apologized for. So it is possible that my wife will eventually come out of denial through discussions with her sister. I had a similar unexpected meltdown with a Barista at a local coffee joint where I was treated rudely. These are mini skirmishes, though my response was sudden and without thinking.
I am located in the U.S., by the way.
Are your 'meltdowns' a new/recent thing?
I'm not quite sure how I feel about you describing being upset (mini meltdown) about someone poking their nose in regarding how much to leave as a tip as a 'glimpse of the beast'
When you said mini meltdown, did you mean a verbal outburst at someone 'taking over' what was essentially your decision?
Autism isn't just about the negatives. We have positive traits too.
