I've gotten a family, but something seems strange...

That's right! I've got a family! It's a family of 5 named the Kellys! I've got 2 parents named Paul and Rosemary, as well as 3 siblings, a younger sister named Annalise, an older brother Cameron, and an older sister Deborah! This means that I'M HEADING TO NEW ZEALAND!!! Although, something doesn't seem quite right... on the form that they sent me about the family, they said the Kellys would host me for 3 months... so after those 3, what happens to the other 9 that my parents paid for? Both parents are wondering about this, and I'm hoping we get an answer soon...
