I just noticed, that if an elder plays tag (or catch, whatever the name is in English), and they have a cane in their inventory, they won't run, but walk sloooowly to catch the other sim while they stand around waiting patiently. Looks quite silly, and takes a lot of time.
Also, Holly Alto visited my house, spotted the leftovers of a cake and ate it all herself. She got fatter and fatter after each plate.
Then, when my sim went to tell her off for rude behaviour, she gives this look:
First time Holly Alto turns out being over-eating, loud and rude in my game. She even burped after eating. And look at those clothes~
(I know the game's just random mostly, but it was still funny)
