How Random is Sims 4 Really?

I see some randomness in my game when I’m not micromanaging which I tend to do a lot because I see sims being specific ways for the most part, and control them.. I’ve seen things, like a grandmother sim sitting down on her granddaughter’s bed with her granddaughter and talking to her. I see a grandfather dancing with his grandson after eating. I see someone coming up and slapping my male sim because he kissed his wife in my movie theatre ( the sim had a pink bar with the male sim and slapped him ( the pink bar was not there because I had played the male sim that way.). Sometimes if you change households you will see you sim is at another lot that you didn’t send them to…….I see these as all random events. In fact many people complained because they didn’t like their sims flirting with people and getting a pink bar when they weren’t playing them.
