Whoa, Who Says Sims Can't Learn?

I am playing a refresh version of my Sim Erik Cantrell. He's currently a Teen who just made it to Proper Celebrity status. He's nominated for Best Song for the very first time. He held a reasonably successful Meet & Greet, so after Services on Sunday, his father took them all out for breakfast at their favorite eatery, Millie's Café. I didn't finish this playthrough yesterday. So, today they are still at the venue. Of all the Sims in the restaurant, I was very surprised that Erik, who had gotten out of his seat, was approached by the Host. I saw him push the male Sim away and managed to catch that picture. What happened next was too fast for me to catch, sadly. Erik SLAPPED the Sim! I guess he's learned to be more clear about his feelings. This is absolutely crazy, but fun! Who knew? I surely didn't. LOL

ETA: Correction on his status, he's a Proper Celebrity at this point. changed it from B-lister.
