text: Tom: Hello, I would like to ask if you have a particular tropical fish I am looking for in your store
  Angela: Which fish?
  Tom: I need a female severum. I just have a male and I would like to give him a mate.
  Angela: How big is he?
  Tom: About 15 cm from the mouth to the base of the tail.
  Angela: We don't have any that big, and if you put too small a female in, he will probably just chase her to death.
  Tom: OK. If you do get any in, or see any, can you let me know?
  Angela: OK, or what I can do is put one or two females in a side aquarium and grow them on. They will be ready in six months, but you won't find any that big in the trade, normally.
  Tom: That's a great idea.
  Angela: No problem, but it mean you need to pay a bit more and I need a payment in advance. Please call in tomorrow and we'll discuss it.
target: Tom would like a female severum to accompany his male. Angela has not got any big enough, but can grow one ready for in 6 months. Angela invites Tom for tomorrow to discuss payments.
