I started doing this with my H a while back and it works wonders. At first, though, he would look at me incredulously as if to say, "You mean we're not going to shift the focus to you?!" When he realized that he could either answer my question or endure my never-ending polite barrage of requests for him to do so, he would suck it up and answer it. Annnnnnnnnd, I usually found out some of the most interesting tidbits in those conversations cause he was already worked up and would blurt the truth out, instead of trying to sugar coat things, or fudge things a bit in order to make himself look better (or me worse).
I still do this with him, because he is easily distracted and often forgets what the question is if I don't repeat it several times and keep coming back to it.
