@bebasim Thanks for the lovely comments :) I have played with a young version of my SS but my elder one is the one I identify with most. Even when I don't play her, she seems to be everywhere. I had one save where every time I saw her she was sad and then it occurred to me that she was losing friends left, right and centre because she had been in the town for a long time and all her friends had been dying off from old age. After I saw her witness the death of a friend, I decided to give her the Stone Hearted LTR in future saves.
The 5x5 is a variation of Charlottesmom's 4x4 Challenge. It was a fun save. Here's a link to my save http://forums.thesims.com/en_US/discussion/913209/clifford-and-jordan-5x5-ts3/p1
