Wife and I are like minded when it comes to scraping or rinsing plates before they go into the dishwasher, fortunately.
I don’t force myself to eat all my food, but will typically do so as I tend to serve less than I might need and add a bit more after if I’m still hungry.
What I mean is that while still eating I (kind of pedantically) normally scrape my plate quite clean such that there is nothing to rinse, like every grain of rice for example, in the interests of not having to rinse off anything before it goes in the dishwasher. This is the thing I haven’t bothered to ask my wife to also do.
