Sim interactions I've discovered by accident

I never send my sims to the roller skating place (because I usually forget to add the pre-made one to my neighborhoods), but since I downloaded a neat one from Laverwinkle Sims, I decided to try it out with my current update, the spare story of Cody. I had no idea the sims could jump and twirl if you click on the floor while they are skating! (and of course, if they are low in body points, they suffer from spectacular falls too, ouch!)

But the cutest interaction hands down is the one of "twirl together" from the picture. I never expected them to kiss, though, for they didn't even have crushes with each other yet! Love is too easy for the sims sometimes.

Have you also discovered new sims interactions by accident?
