I had my sim, Billie, give a Charming Introduction to someone she just gave a sing-o-gram to last night. She did no further socials with him and went on to her next gig.
I switched back to her boyfriend, Tristin, who was using the treadmill at the house. The sim Billie had just met apparently immediately left the theatre and went to her house, uninvited. He walked into the bedroom and turned on the portable radio. Tristin stopped what he was doing, walked in, and slapped the guy. I then got the "I can tell you have some issues" chat comment, although no one was in a group.
I've been having things like this crop up lately. I had a paparazzi in Union Cove walk up to my Actress's house at 3 a.m. and ring the doorbell. It was kind of creepy.
