I read this in Kafka on the Shore:
The girl frowns and gives me a hard look. "You don't watch at all?" I shake my head silently. Wait a sec – should I nod or shake my head here? I go with the nod.
I want to know if the author is rconsidering using "shake" or "nod" for concern of them being semantically precise or are they(the author) in confusion themselves whether they watch or not in actual? And also why are they saying that they go with the nod when they actually have shook before?
