How come the private school principal won't come over to my SIMS house?

My SIM has perfect grades and a good job. Her house is huge and really nicely furnished. She cooks lobster or porkchops everytime, and her parents are both employed. But the principal always comes, gets out of the car, and gets back in and drives off. WHY?How come the private school principal won't come over to my SIMS house?
I've never had them leave right when they got there but to get them in private school make sure one of the parents has a lot of cooking points and the other has a lot of charisma points then invite the headmaster over and have the one parent with lots of cooking points make a meal and the other one can give him a tour of the house and schmooze and make sure everyone is at the table eating when the headmaster is





that's how i do it and i make sure the house is clean of course and put stuff with lots of room points around the house and make sure everyone is in a good mood when he comes over use the cheat maxmotives if you have too





good luck!How come the private school principal won't come over to my SIMS house?
MAYBE HE DOSNT KNOW WHER YOURY SIMS LEAVE.
