Has anyone else run into Sims who react negatively to pretty much every interaction you try on them? I've encountered this with both Dayvid Musgrave in Moonlight Falls and Derek Khan at university. It's not a matter of badly conflicting traits -- Dayvid is Friendly, so it baffles me even more. Derek is Avant Garde who are "harder to impress", but I've chatted and befriended other Sims with that trait just fine. Nor is it a matter of trying to chat with a stuck-up celebrity: neither of them had any stars. And they weren't upset with me about some previous faux pas either, it began with the very first interaction. At first I thought maybe high-level Rebel Derek had issues with an "outsider", but no other high-level social group members did, and that still wouldn't explain Dayvid's dislike for my Sims.
I didn't try talking to Dayvid again, but with Derek I persevered to see if it'd stop if my fairy would manage to become friends with him. It did, but sheesh -- that took a long time and many double minus sign setbacks.
Another curious discovery I made in the process of befriending him: AUTONOMOUS interaction options, either from him or from my fairy, didn't trigger his attitude. Only the ones I actively selected did. Before we reached the friends stage, the only interactions that Derek didn't slap me with big red minus signs for were Enthuse About Exercise (which is odd as neither he nor the Sim I had talk to him are Athletic) and Playfully Pester (fairy interaction). Oh, and Apologize.
