ah oui hein?

A slightly more polite way to say "Anyway..." or "Moving on..." in response to something you don’t find particularly engaging (mildly interesting) or not worth further discussion (inconsequential information), with a reduced probability of hurting or ignoring someone entirely. In French Canadian (Quebec), "ah oui hein?" is an informal / colloquial follow-up interjection, often said in a nonchalant manner to convey a mix of polite acknowledgment and mild indifference. When used genuinely (i.e. not sarcastically), the speaker is effectively being polite, demonstrating a willingness to keep the conversation going despite a lack of immediate curiosity.
