I'm playing sims life stores and I invited theheadmaster of the school over for dinner HE WON'T LEAVE!?

He just stood there after I gave him a tour and schmoozed for a bit. So now I can't get my points for dinner because he won't eat! ITS UNNATARUAL! I've tried everything! Calling him over for dinner but everytime I choose an action for the headmaster it just utomatically deletes the action and it's says that time has ran out. Why isn't he gone? Can someone help me out? Tell me why this happenning I NEED HIM GONE! HES UGLY! PLZ! HELP!
