I am a literary prostitute

This evening I scared the bejesus out of The Wife when I started screaming about something I read in the paper where someone was quoted as saying that what I do for a living was "a terrible form of prostitution." Along with other related things that have happened today, reading this statement really pissed me off. We were watching an episode of "Bones" on the DVR and it happened to be about a call girl who was murdered. The Wife said something along the lines of it not being uncommon for a prostitute to be murdered and then said "well, maybe if you are a literary prostitute."
