An Anti-Gricean duet: No offence meant; None taken

Yet another:

You are the daughter of a bitch
-- says the tomcat to Lassie.

She looks disappointed.

"No offence meant", you know.

"None taken", she _THEN_ says. Because she needed the reassurement that none was meant to take it".

Grice writes:

"The kind of moral, or more or less moral, distaste for things is one which I feel that, as someone brought up in the enlightened 'pinko' (at least on the surface) atmosphere of Oxford, as it used to be [remember I lose interest in
anything post-1967. JLS] I understand very well. We are in reaction against our Victorian forebears [who made beautiful bronze busts, though. JLS]; we are independent and we are tolerant of the independence of others, unless they go too far. We don't like discipline [but why did fellows a la "Another Country" ended
up in dictatorship Russia?] (Conception of Value, p. 58).

"And we go by Freedom and Resentment".

--- Strawson's point:

"If no offence was meant how can one be taken?"

The repartee, "None taken" is super-superfluous on the face of the co-conversationalist having just said that none was meant.
