I think one of the cutest animations was when I had a generational family, and I would see the Grandmother come into her teen granddaughters bedroom and just sit on her bed and talk to her. I now also love to see the couples sitting on benches looking at the sky and such ( since the love struck expansion came out ). Oh, and when growing together came out I loved the infant animations, the baby rolling over in bed was particularly cute. Since growing together there are such cute animations for infants. Growing together + Infants really did change the game for me, just like toddlers did. I really like being able to draw in sims from the gallery for sims to date too with cupids corner. Cottage living, and horse ranch have some cute animations too for the animals. I laughed so hard the first time I saw my sim get bucked off their horse.
