I really love naming and personalizing all those little aspects of my Sim's lives. I am going to have my current Sim (a former Celebrity Chef turned Bakery-owner) write a series of cookbooks with baking-related names ('Are you Bread-y?', 'Muffin To Worry About', and 'Bake it 'Till You Make It' are a few I have brainstormed already).
I even change the lot names for households I don't plan on playing. It's just nice to see my personal style here and there around the game.
