What Do You Do When You Finish?

I don't play legacies or challenges (too many rules and restrictions for my taste) but I like to take a lot of screenshots capturing important moments in my Sims' lives (first dates/kisses, graduation from college, engagements, birthdays,etc.) I save my favorite Sims and use them as background townies in other saves if I don't have a particular Sim in mind to play. Hope this makes sense. :)
