text: Robert: Mom? Where are you? I'm home and nobody's here. 
  Mom: My sweetheart, I'm on my way home but caught in a traffic jam. Absolute chaos here! Can't tell you how long it will take.
  Robert: And where's dad?
  Mom: He should be home any moment really. He would phone if anything kept him.
  Robert: I'm hungry.
  Mom: Darling, wait till dad comes. He'll fix you something to eat before I come. There's now so much commotion and police here, and ambulances, and recovery vehicles. It'll be over soon.
  Robert: Mom? Can I go over to the Woodies? Sure Helen is already serving dinner.
  Mom: No, darling, please don't. Dad is on his way and we're starting to move too. I won't be long.
  Robert: But I'm hungry.
  Mom: Oh Robert! Please stop being childish! Eat an apple. Or drink some juice. I think we are moving.
  Robert: Where are you exactly? How long before you're home?
  Mom: Can't write now. Here's my location. <file_gps>
  Robert: But it's still miles away!
  Robert: Mom?
  Mom: Trafic lights on Carrington Xing.
target: Mom and Dad are not home to prepare food for Robert. Robert is hungry but he cannot go to the Woodies for dinner. Mom will be home shortly.
