I’m not autistic but I was often called out as a kid for not showing any emotions on my face until I got angry.

Later in life I discovered that in the old world, Lakota men were expected to have an emotionally blank expression. And it was often misunderstood by white people.

There was a group of young warriors that called themselves Ugly Faces and would try to make the hardest and scariest faces during hunting and battle. They were enjoying the highest of joy but trying not to show it.
