It gets on my nerves when someone's pencil makes that SCREECHING NOISE while they write a short answer on a test. =A=;;; It bugs me a lot because you don't really need to press on a pencil THAT hard. I press on my pencil pretty hard but I'm careful so I don't make that noise and annoy the hell out of everyone around me. If there's a way to explain it, it's like when the tip of a pencil is flattened on one side and the person using the pencil INSISTS ON USING THAT FLAT SIDE. It also gives me shivers that I can't control ;A;
