I used to always make a seedy bar in every town, so that certain Sim couples can have that kind of drama where one half of a couple catches their significant other having a bit too much fun somewhere behind their back.
There were levels of humanity and reality included in the earlier games that could incorporate into some varied real life type of drama and stories.
Now it's all replaced with smartphones and talking toilets, and the facets of humanity that came together to make our sims so multifaceted and interesting has been completely stripped out. Everything is geared around technology and fad addictions to an extreme, and regular life has been basically thrown out of the franchise. We need different tools to bring those facets of humanity back, and this type of thing is one of them.
Our adult sims need to live lives that are made of the complexities of adult life, not act like little kids always obsessing and building their identities around the latest fads. We need real adults in the sims - good, bad, ugly, and crazy of course.
