I had a situation where the four oldest kids in the household all went to Uni at the very same time. Shared a dorm and everything. It was fun. However, since one of the now YAs was a Global Superstar, I failed to unlock the security gate around the parents' home before they left. Dad invited them over for a visit, but I found them all in the street outside of the home. There was no way to unlock the gate, either, as they were no longer living on said lot. I wasn't inclined to have them all move back home, either. So, that's my story.
