This is what keeps me from accepting the invites when they pop up. Last time I did, my sim showed up and no one was there. I waited several sim hours....so I figured I'd have him cook since he was getting hungry and he was at his girlfriend's apartment and figured they could have dinner when she finally did come home. And since no one was home, maybe he wouldn't get yelled at. ;)
Ha! Guess who suddenly appeared literally out of nowhere to yell at how inappropriate he was being? She then promptly takes a quick meal out of the fridge and begins to eat. So I had him grab one as well and she was totally ok with that at least.
BUT later when he invited her over to his house, she makes a beeline for his fridge and begins to clean out the spoiled food and take out the trash. I mean...great, thanks. Saves my sim from having to do it but why the double standard?? Lol
