Erin and Kristina were drove by their father to school before he goes to work himself. Their Mum, being a housewife, stayed at home with Nanny Lisa and other housemaids.

Before the two sisters left home, Erin seemed to notice the different behavior of their Mum. She's not as cheery like the other days. She seemed to be going through a difficult time.
