Share stories of when your sims were being creepy

I was playing a household that had Summer Holiday as the mother of a bunch of kids. One day, one of the children brought a friend home from school and the two children were playing dolls in the basement rec room while Summer was off in the corner practicing guitar. When I switched control to Summer to make her stop playing guitar, I noticed that she had a whim to flirt with the KID that her son brought home from school. I was a bit mortified.
