text: Laura: Mom had asked me to go grocery shopping before she left for work this morning, but I need to finish my school project. Can you go for me, Martha?
  Martha: I guess I can. I am done with my homework. What did mom want you to buy?
  Laura: Well, she wanted me to buy enough groceries for the whole week. Besides meat, some fish and vegetables, we can buy whatever else we want for snacks and breakfast.
  Martha: What do you want for breakfast?
  Laura: I guess some cereal as usual.
  Martha: I do not want cereal every day. I will buy some pancakes and syrup then.
  Laura: Get the new Fine Food pancakes in the frozen food section please. I want to see how it tastes.
  Martha: Do we still have enough coffee and cream for mom and dad?
  Laura: Yes, we do. Talking about coffee and cream, you better buy some milk also. We almost ran out of it.
  Martha: Next, what do you want for snacks?
  Laura: Some chips would be fine with me. You probably want your chocolate cookies.
  Martha: I better write down all these things; otherwise, I will forget them by the time I get to the market. I would hate to make two trips to take care of things.
  Laura: Right! As far as meat, mom wants some pork and some chicken.
  Martha: Just any kind of pork?
  Laura: I forgot to ask mom about that. Anyways, you can ask the butcher for his opinion. He knows what is best.
  Martha: How about fish?
  Laura: Mom wants some salmon and some catfish. Make sure that they are fresh.
  Martha: How much salmon and catfish should I buy?
  Laura: Oh, buy four pieces of salmon filet and four pieces of catfish filet. Mom does not like to get the whole fish.
  Martha: Are these fish fillets sold by weight or by the piece?
  Laura: I am not very sure. Just buy four decent sized pieces. Not too big and not too small.
  Martha: ok, let me try it out then,
  Laura: sure thing
target: Laura was asked by mom to buy groceries for the whole week, but she must finish her school project, so she asks Martha to do the shopping. She should buy some meat, fish, vegetables, some snacks and something for breakfast.
