I had one heck of a "hmmmmmmm" I just might have AS moment today.
I had a lady paying for her yarn and she was telling me a long drawn out story about watching her grandchildren, who had salmonella poisoning and how she got it and was so sick for two weeks. Not wanting to be rude, I smiled and nodded, looked her in the eye now and then said things like "oh my", "nnnoooo" and "that would have been awful". Small talk is an effort.
My boss was sitting at the work table a few feet away and when the lady left she smiled and said, "I could tell you were
really interested with your "Oh mys" and " I sees". I wasn't sure if she was being sarcastic, I thought she was, or if I had just committed a faux pas of some sort. I sat and worked on my project for an hour trying to figure this out and when she came to sit with me I told her I didn't understand what she meant when she commented on my talking to the yappy lady. She laughed and said that she was being sarcastic but it wasn't a bad thing. She told me she could tell that I was just feigning interest because my voice was completely flat

but the yappy lady had no clue. She informed me that it is best to do that, and she thought it was interesting how I dealt with her, like a little robot.
Fortunately, my boss has a family member with AS and had dealt with me and my boys for years. She finds the traits that I show so interesting that she read Tony Attwood's book and asks me about how I see different things that go on at work just to get more than one perspective. I am really glad I met her.

See, that is what I meant by being the office cat. Of course, we have to detect mice and keep the place free of vermin, but it is nice to get your belly patted every now and then.
