Parker leaves the country

I arrive for parent orientation at Parker's school and am getting side ways looks from the office staff and then again from her friends mother's. One of them approaches me and says "Is Parker back?" I respond with "Where did she go?" ...apparently at the end of last year, she told all of her friends and the entire school that she was moving out of the country. They threw a big party for her and everyone cried.....why am I surprised.....
