text: Susan: Will you go shopping with me some day this week?
  Maggie: what do you want to buy? 
  Susan: Derek wedding dress :-)
  Maggie: Who’s getting married?
  Susan: My sister:-) And she asked me for assistance ‘cause she doesn’t know what she wants to buy :-(
  Maggie: Oh. C’mon, who’s supposed to know better than she?
  Susan: I know. Would you help us? Pleeeaseee :-)
  Maggie: All right, I will help you. When does she want to go?
  Susan: Saturday. Sunday at the latest.
  Maggie: Oh no, I’ve got plans already. I don’t think I can go...
  Susan: C’mon, it’s my sister!  If we don’t buy this dress now, it may be too late next week!
  Maggie: Ok, maybe I’ll find some time in the morning?
  Susan: Really? Will you?
  Maggie: Will that work for you?
  Susan: Of course, morning would be great!
  Maggie: I think 10.00 would work best.
  Susan: Oh, sure! 10.00 is just fine:-)
  Maggie: OK, we’re set then. Talk to you later!
  Susan: Thank you:-) See you on Saturday morning! 
target: Susan and Maggie will meet on Saturday at 10 and help to buy a wedding dress for the former's sister.
