Had in TS3 a Sim get the "My Best Friend" (robot aspiration). This was a legacy and this robot lived to several generations also being a caretaker and butler to the family.

Adopted a child by accident (wanted to get a pet). This was the first time I had chosen adoption in The Sims. I hated her initially but she was pretty dedicated, nice and also a Genius, so I fell in love with her as a player.

A floating house for my witches. They were such a pain to build in TS3 though.

Downloaded some edgy mods and had a sim set up as a prostitute. She had a younger sister whom she tried to raise the best she could, even though they lived in shit. It was pretty sweet until the young sister died AS SOON as she became a Young Adult. Then it got very sad.
