I had a teen who asked someone on a date after school. I gave him some introductory interactions to start with. While I was checking out what was happening with the rest of my overstuffed household, he decided to go home. I cycled back to him on his way home and sent him back to the date, who, thankfully was still there. As soon as they started interacting again, a nearby Sim was visited by the Grim Reaper. Yes, they died and everybody around the lot was in mourning mode. By then it was too late to continue, so I ended the date and sent him home. Apparently, it was a 'Great Date'. No romantic interactions because he didn't have time to do so. Go figure.
