Sometimes I like to do a game of randomness. I set Free Will to High, but I use a coin and a die to decide what each Sim in the house will do. Flip a coin for something inside or outside and just pick different categories of things you can do and roll the die. You can divide those into separate subcategories and roll the die again until you pick something for your Sim to do. You can rotate through each member of the household. You can also do this for social interactions. Flip a coin to pick someone in the household or outside the household. Then, roll a die to pick an area to go look for someone outside or choose a family member to interact with. Then click the person that you select and roll the die to pick what interaction you will have.
