Sometimes a cigar is just a cigar.
Everything is not a conspiracy. And unless you have been around crazy people (and I have), real bat-shit crazy people...you can’t understand that they don’t act rationally. I don’t mean that as an insult. But unless you have been hip deep in it, you will still expect “normal” behavior. It would not have surprised me if he sat down afterwards and ate popcorn.
His behavior is exactly what you would expect from a deeply crazy person.
I used to work as a bookkeeper for a private social work agency. Some of our clients were schizophrenics. We had one client who refused to take his meds and preferred living on the streets to living in a monitored group home. He came from a very wealthy family and was once a brilliant young man with a bright future and promising career until the illness took hold of him. He would only come in for therapy to get his small monthly allowance that his parents set up for him. He could be calm and rational, even polite and kind one minute and the very next minute would go off in a rage.
He absolutely terrified me.
