mouth sounds

At my “job” (internship) it’s really quiet because people are usually working on different writing and research projects, so we usually communicate through gchat. Even if we’re sitting next to each other. Which is fine. I just put in my i[Head]phones turn on my iTunes and iCoast until lunch. But since I only work about 6 hours a day, there’s no time to “take lunches” so I have to eat at my desk. But I’m always concerned about how loud I’m being. Eatting in/Inner ear/outer ear/earphones. It's a disaster. So I spend my entire lunch munching my food at a volume I know won’t distract others from their tasks, but try to maintain a pace where I can finish before my rice gets too cold. It's absolutely awful. I think I need a new “job”...
