One of the agents who works in my office -- we'll call him Nameless -- has several habits that cause a reaction in me, among them a determined and exhaustive cracking of every finger joint in every possible direction. Really. Every direction.
Well, he has another habit -- one which really causes every nerve of mine to stand up and shriek aloud. We keep a few bowls of candy in the office, it is my job to keep them full of mixed candy, and I enjoy that part of the job. Right now there is a slight preponderance of hard candies in the mix, peppermints, butterscotches, tropical fruits, etc. Lots of suck-upons. And Nameless picks one up, unwraps it and chews it up right there and then. He is swallowing its pulverized form as he reaches his office again. CRR-RRUN-NNCH, CRR-RUN-NNCH, CRUNCHY, CRUNCHY, swallow. I can hear his teeth splintering into shards as he does this. Brr, shudder!
