A coworker once told me that hitting your head makes you smarter because it pushes your brain cells closer together.
I asked him what that meant for people with traumatic brain injuries from accidents. He confidently insisted—multiple times—that they were actually the smartest people ever.
According to him, people in comas from brain injuries would wake up 20 times smarter.
So… yeah. Apparently, brain injuries create geniuses.

One time, someone found out I was raised atheist and asked, “But if you never read the Bible, what’s stopping you from m**dering and rping people? You must not know right from wrong!”*
They were genuinely shocked when I answered, “Empathy.”
Like, they looked at me as if I had just given the most ridiculous answer imaginable—as if that somehow didn’t make sense.

A former employer once accused me of lying about the severity of my autism because I did well in the interview but struggled with the actual job.
Mind you, she was the one who specifically sought out an autism support organization to hire an autistic employee—for her ABA therapy business.
Later, my sister pointed out that this employer wasn’t giving anyone enough instruction to do their job properly, neurospicy or not. So, no wonder I “failed” in her eyes.

When I was 17 in high school, a classmate seriously asked me when color was invented. She thought old black-and-white movies were proof that everything used to be in black and white.
On a school trip to a farm, the same classmate also believed that cows were either born big or mini. I had to explain to her that the tiny cows we saw were actually calves and would grow into full-sized cows.
