Or this guy, Randy, whom I will be dating, I think (a very nice guy, clearly). The job is a little boring at times but, he says, the job security is such that he has to commit a criminal act to be fired by the company. A very secure company, not a start-up. Published a good technical book 10 years ago that still sells. Polyamorous by conviction and has great friendship relationships with all ex romantic partners, so no drama or crisis that most other people experience on a daily basis. Has a hobby and regularly invites members of his hobby club to his apartment for meetings, so, socialization. Goes out, so, more socialization. Does not happen to have a lot of sex life right now, but at least something and on a regular basis, so, check mark. Good income, another check mark. Loves what he is doing with computers. Watches a lot of movies, so, has some interests outside work and hobbies. So what is the problem? Nothing situational. But, reports depression for which he has finally found an effective medication after trying several bad ones. He does not have exogenous problems - it is just an endogenous illness.
