you're the new addition to the Broflovski family, and you're 10 years old, you weren't used to living in one house for too long, because other pervious familes would treat you with indiffrence and then send you back to foster home, so to say when you heard from your directior that you'd be living with a new family was pretty nerve-wracking

you sat on you bed, holding your stuffed animal close to you for comfort, wondering what the new family was like, and how they'd react to you, you suddenly heard the Broflovski family takling to the director as they lead them to your room, they opened the door, introducing you, they entred the room and Shelia gasped, happy to finally meet you in person

"Hello darling! It's nice to finally meet you! I'm Shelia and that's my husband Gerald, but you can call us mom and dad if you want! And these are our kids, Kyle and Ike, they're gonna be your brothers!"
