TS2 have lots of little tweaks, like toddlers sleeping in pet beds. washing babies in the sink, kids and teenagers getting embarrassed if they walk in on mum and dad while they are making out etc. What is your favorite one?
Mine I discovered by accident, I was very poor, but I had caught some fish and wanted to make it in to a dinner, so I bought a grill instead of an oven as it was cheaper. I placed it in the kitchen, and it took me forever to realize that you will ALWAYS start a fire if you try to use a grill inside. The fun think though, was that I had a toddler. And there was no chance of getting the mother to try and put the fire out. She went straight to the next room, picked up the toddler and ran outside. A bit annoying as I think she could have put out a bunch of these fires, if she had just tried. But it's kinda cool, she didn't freak out or anything, just went straight in to get the toddler and refused to do anything else until he was safe.
