Well, Whenever I'm eating, I'll occasionally grind my canine teeth against each other. That really makes me cringe. As does cotton. Odd enough? Whenever someone rubs a cotton ball, or I use a Q-tip, it makes me shiver kinda violently.
Same here! (About the teeth) I do that and then I'm like OH GODDD >_< It's horrible. And also about the Q-tip thing, agreed there @_@;
