Sims with odd routines

Most of my most played sims don’t have treadmills, but they have radio’s and a few of them are always turning it on and dancing, when I don’t have them out jogging around the neighborhood. Some single sims who garden have taken to talking to their plants as well. Some married sims seek each other out to talk, and one married couple with a toddler are always flirting with each other which is cute. I used to have one grandmother who always sought out her teenage granddaughter to talk to, she would sit on her bed and talk to her ( I think they both had the genius trait ), I thought this was very cute too. And then there are some sims who are always seeking out the chess table. I don’t really see these things as odd, but they do have routines.
