Yeah, sometimes there are people that you can tolerate, but only now and then. You might think, "Well, I wonder how old so and so is doing?" and you go visit them. Then it is the same old thing as before, but you tolerate it. Sort of like when a kid doesn't really bond with a relative, but all the others do. Sometimes you have a friend who has another friend who is clingy and tags along. So you just tolerate it. You could get tense, grossed out, annoyed, creeped out or just bewildered by the other person sometimes. Then sometimes you could be pleasantly surprised. There could be some new moodlets where you are sort of passive aggressive, secretly annoyed or laughing under your breath. You could pull another sim to the side to "have a little talk" about them, inside joke, gossip and such. Sometimes you could get the urge to suddenly go for a jog, go to the bathroom, get a bit of fresh air or just about any excuse to get away. You could approach the sim you don't care for and have various fake outs and excuses to get away.
It would be really funny if you could call your best friend or text them "save me!" and then they call you right back with some urgent message where you can have the excuse to get away from there.
Then if you tolerate the person for a certain amount of time you could get some moodlet such as "Nailed it" or "Gracious" or something like that.
If you got away from them, you could have moodlet like "Smooth escape" or something where you feel pretty smug about it. Then if you feel a little guilty about you could get a moodlet like "twinge of guilt".
You should also be able to tell other sims about it if you want to. It would be a chat feature and you could do like "I escaped from" and then click on a picture of the sim you escaped from. Or you could do "I tolerated" and you can chat about it. Then the other sim can respond like "You go girl!" Or "I know, right?" or get kind of angry about it if they like that other sim.
I am kind of introverted sometimes and I get enough of people, so I just feel "all peopled out". There is a shirt I saw online that said something like "I peopled today!" and that would be a good one for me sometimes. A bad moodlet for introverted sims could be "All simmed out" then a good one could be "I simmed today!"
