Can you guys please share examples of shit-tests you've run across in your respective marriages?

I'm legit autistic. I've been with my wife since sophomore year of high school (20 years ago!) and I still can only consistently read four basic emotions on her face with any degree accuracy.

I know reading emotions has little to do with spotting shit-tests, but I mention it here because it's a good example of the fact that I'm pretty dense when it comes to classifying social interactions.

I tend to only learn things like this by memorizing lots and lots of examples. I can generalize a bit after that, but not a whole lot.

Thanks!
