Ok so, once upon a time, I had a large household of young sims about to become adults, but couldn't find a nice female townie for the second oldest brother. So I made a family with a single father and two daugthers, Devin and Meghan and paired Devin off with the brother connor, and they become my main family. Fast forward about a decade or so in sim years and Devin, who is a painter, makes this painting that looks extremely similar to her, except with short hair. So in my story she painted a portrait of her mother that died when she was very young.
Here is a picture of her beside the portrait for comparison. (I'm new to posting pictures so fingers crossed this works.)
Gotta love when your sims backstory writes itself.
