" Counting is a symptom, but counting symptoms is also a symptom, a tick plus ultra. I've got meta-Tourette's. Thinking about ticcing, my mind racing, thoughts reaching to touch every possible symptom. Touching touching. Counting counting. Thinking thinking. Mentioning mentioning Tourette's. It's sort of like talking about telephones over the telephone, or mailing letters describing the location of various mailboxes. Or like a tugboater whose favorite anecdote concerns actual tugboats. "
