Do you use the Club system?

I actually use the club system all the time. With the club system, my sims don't suddenly leave at 9 PM (or whatever time it is), they get boosts to skills, and the sims that are members but that I'm not playing also will earn skills while I'm not playing them (which I love). It is the perfect way to make friends and fulfill the friend of the world aspiration. Have a future couple in mind? Make them join the same club. It's great.

I was very annoyed Cats and Dogs only allowed a new "earn Vet skill faster" perk but did NOT add it or any pet interactions to the club activities list... It seems like a huge oversight.
