Say you don't quite make it to the bathroom, and end up leaving an unfortunate puddle in the hallway. I'm guessing you'd be embarrassed. So will your Sim, and that's gonna affect their mood until they take a brisk shower to get energized, or go fishing to feel relaxed. Then, when they catch a fish and mount it on the wall, they can think about how happy it made them, on and on into infinity. With Sims 4, actions are more than a series of disconnected tasks. This time around, Sims display dynamic behavior and emotions that directly relate to the world around them, making the Sims' world feel that much more real.
