I used to have this mod. Almost one hundred percent it was called less social rejection. I foolishly deleted it a few weeks ago, thinking it was more realistic to have sims accepting others whenever they please, that this mod would not make an important difference and hence would not be missed. The thing is, my sims are acting like jerks on each possible occasion. One just does not reject a friend's hug or refuses to dance with them, no matter if we are talking about a three year friendship or a three week one. I searched in many sites, since I do not think it was here in MTS, but I found nothing. I barely remembered sims could be so antisocial when making friends. If someone knows where to find this mod or something similar, I would deeply appreciate any information! Please, friendship is very important. Do not let my sims die alone

TwoJeffs' "Social Sanity Fixes" - Admire, Dirty Joke, Punch You Punch Me, and Friendly Hug only attempted if there is a good chance of acceptance (see the readme file)

Squinge's "No Autonomous Socials" - http://www.insimenator.org/index.php/topic,94748.0.html

Well, oddly enough, I do not have Sanity Fixes in my downloads folder. No Autonomous Socials does not really fit my likings, so I will try out TwoJeffs' mod! Thank you!

Edit: This might work for free will, but I must add that what I was really looking for is a mod that makes me feel more secure when commanding my sims. Um, I find myself hesitating a lot these days, since the possibility of rejection is very unpredictable now that I deleted this mod
