I think that's one of the cases where it didn't work for me. When I put the sims on our new computer and started playing that house, I had him invite her over while Mary Sue was at work. Just as they were about to jump under the covers, Mary Sue came home due to a demotion from a chance card, and though I wasn't planning on getting him caught so soon I couldn't pass up the semi-realistic scenario. (Because how often do sims ACTUALLY come home from work early?) She spazzed, icon-over-head and slapping and everything, but when I checked her memories later there was no "Caught Daniel Cheating" memory.

...I love their opening screen now though. Everyone is angry and turning away from one another.
