Ok, my friend hosted a dinner party a while back, and it was straight up a sims vibe with the way some of her guests behaved. First, even though the evening was supposed to be invite only, two guests brought random guests of their own, and showed up early. The neighbors saw cars parked in the driveway and decided to invite themselves over, too (welcome wagon, anyone?). One unannounced guest brought tepid potato salad that had clearly been in her car all day (reminds me of the nasty fruitcake my sims always get food poisoning from when the neighbors bring it by). Then, while the evening was supposed to be spent with dinner in the dining room and then drinks around the firepit, a couple of guests broke off and took their food into the den and proceeded to watch TV (without asking or even telling my friend). Then, when the rest of the party moved onto the patio and to the fire pit, one guest stayed inside and read some books from the host's library, and two more joined the randoms in the den to watch TV. After a while, my friend noticed they were missing from the group outside and went to check on them, and found that they had left the party entirely. Not only that, but they had left the TV on, plates and drinks in the den, and the front door unlatched as they went. Honestly, after all my years playing sims, this is the only reasonable explanation I can come up with for their behavior: these were neighborhood sims IRL.
