Something that stuck in my head was when a sim couple split up and the guy moved out, the gal was devastated for days afterwards.
She'd sit at the table to eat and if I zoomed in close I could see her lip trembling as if she was about to cry. And when she went out to do her gardening she could water the plants with her tears.
She looked so sad all the time, it broke my heart lol. And the strange thing was that her best friend suddenly started turning up at the door every day as if she was coming round to cheer her up.
