I had a job when I was 18 years old as a night attendant in an insane asylum.
Yes, that is true, it was over 40 years ago.
I learned early on that it was a complete and utter waste of time and resources
to try to “understand” why crazy people are crazy.
but when an otherwise demonstrably intelligent person does something “insane”, you look for an explanation.
Paraphrasing a writer I cannot remember:
Normal people are normal in the same way; crazy people are crazy in a million different ones.
