Remember the fire in Houston at that hideous building? It turns out that an LVN working for a cosmetic surgeon started the fire because she had not finished a project the doctor gave her. Whenever I've not been able to complete a project I usually just whine about it, starting a fire in the office has never occurred to me.
How do people have jobs that require critical thinking and then just one day become batshit crazy? Somebody ask Warren Chisum, I bet he knows.
