@LaBlue0314 It's so funny when your sims' arms follow something at the other side of the town.
Once I had a sim at a festival who started hitting on a guy. She asked him to slow dance and he accepted, so she raised her arms to dance with him. At this exact second, the festival closed, so the guy started to leave with all the other sims. My sims' arms went crazy and followed all of his movements as he was going down the stairs, round the building and leaving, as if she was screaming "nooo!" with horror and frustration. It was hilarious.
