It starts early

Yoshi was washing her face in the bathroom while Vian was playing with the bathroom scale.

Yoshi: Why is it upside down?

Vian: Appaaaa

Yoshi: Appa did it? 

Vian: Appaaa

Yoshi: oh, appa did it 

Vian: Appaaa Appaaa

Yoshi: no Vian, you did it 

Vian: (silence)

All of this happened while I was at work. Appa means dad in Tamil.
