Rekindling relationships after raising children

When I have a couple (usually I play single moms), I have them play chess at the end of the day, and, if there's time, have a bit of woohoo before bed. That's one of the things I truly appreciate about S4 - it's not as hard to maintain relationships between family members because relationships don't decay as fast as they did in previous versions. I also like the ability to start a three-way conversation between the child and the parents while eating dinner or while two of them are playing chess.
