Comedy of two (t)errors

Dramatis personae:
Mommy: a middle-aged, curly-haired woman with occasionals streaks of good temper. She walks around as if the whole world is going to collapse on her.
Boy: a puny little fellow who scuttles around like a rat but with an eye that doesnt miss anything even when he doesnt seem to be watching anything. Could be about 4 years, but doesnt look more than two years of age.
Girl: a short, round-faced two-year-old who seems as tall as the Boy. More stubborn than the Boy.
ACT 1: Scene 1
The phone rings. Mommy rushes to the room to pick it up. Two kids are sitting in the drawing room eating cakes.
Mommy spends 5 minutes at the phone grumbling about the kid's pranks and tantrums to the mother-in-law.
Meanwhile she notices that the kids have finished snacking, pulled a stool to the washbasin, turned on the tap and are washing and washing their hands like Pontius Pilate. The washing and lathering goes on for a good 3 minutes before she decides to end the phone conversation.
She rushes to the room, shouts at the kids who scamper away. She picks up the bottle of Lux liquid soap to find it almost empty. Nearly half its contents have gone down the drain.
Scene 2 will follow as and when time permits.
