@dragancaor finally someone else is having the same problem. It would be an annoying bug if you are particular on the relationship health between sims.
I saw this happen too. I saw a jogger going by my house. I thought, 'YAY! New friend!' I used my ability to politely greet said stranger, and got a negative relationship appear over their head. Since I had used a polite greeting they were still in the green, but another stranger appeared so I went to greet her politely. I then compared the amount of green relationship between them to see if I had imagined things, but no, those two red - -'s I saw were there. Eve had more friendship built up with the second stranger than the first. It had not been my imagination after all. I was highly confused because a polite greeting ALWAYS gets a positive green reaction and that had been all the talking I did.
He wasn't the first jogger I flagged down with a polite greeting either and this was the first time I noticed anyone randomly giving me a relationship hit for a positive interaction, mainly because it was such an obvious positive reaction that I never get tired of watching. I think the little stream of warm orange going from Eve to the person she's introducing herself to is precious and the adorable little wave they give afterwards just makes me smile.
Seeing this thread makes me feel a little better. I'd convinced myself it MUST have been him being upset I interrupted his jogging even though that was never a problem before.
