The tone of the question was likely to offend and elicit a prickly response unless he has another job that he is very stoked about.
My guess is that he pieces together a living from a bunch of things like movie reviews, music lessons, freelance editing, bartending or waitering, who knows what else. It is a pretty common thing to do. I know a lot of semi-professional actors, musicians, writers, etc. who get by doing a series of short-term jobs to pay the bills. Like Cole, they take their semi-professional hobby a lot more seriously than their job, and are decent, but not world-class at it. If I run into one of them and ask them about their life, they are going to tell me about the play they are in, or how have a new regular gig at a bar, or how they just got a story accepted in some magazine. They are not going to spend much time telling me about how they left their dishwashing job and are now busing tables at a different restaurant.
