I've tried all kinds of approaches. The only ones that ever worked were based purely on the person communicated to, not how I communicated. (ie, the person cared)

I've had nice conversations about it, the person listened, but was only able to be reasonable quiet for a short period of time. And then simply reverted. (they didn't care)

I found the best solution was simply to face this head on and deaden my reactions to it. This reduced my reactions to a living tolerable level.
