It was just a normal day until one day. They had a new sibling in their family. Their parents brought a little girl to the house.

Karen (their mother): "Avrille. Stone. Meet your new little sister. Mar."

Kevin (their father): "Say hi to her."

Avrille (Stone's older sister): "A new rat lab?"

Stone: "Hi..."

Karen: "She's 8 years old. Take care of your sister. Me, and your father are going shopping."

Their parents left the house.
