text: Sheri: Hi girls! 
  Sheri: Wanna join me for ice swimming on Saturday morning?
  Eileen: Ice swimming?? Never!
  Roddy: wanna know more
  Sheri: Well, I went with a friend of mine
  Sheri: She's already experienced in it.
  Sheri: there is a group of people who meet every Sat from October till April and swim in the lake for a moment
  Roddy: I cant even think of that!
  Eileen: Me neinter!
  Sheri: But you know, it may be hard in the beginning, but it makes you feel so good after
  Sheri: the skin becomes softer, the blood circulation is so much better, and your organism is stronger
  Eileen: Ive read somewhere its really beneficial
  Eileen: but, you know ;) I probably wouldnt dare
  Sheri: :D
  Roddy: and do you need to prepare in any special way before?
  Sheri: not really. 
  Sheri: The more experienced swimmers help the new ones, give them suggestions, etc
  Sheri: its all very safe
  Roddy: No doubts about it, but Im not really sure to be honest... ;)
  Eileen: Id like to see it live!
  Eileen: can I go with you on Sat, just to have a look?
  Sheri: sure! 
  Sheri: and you, Roddy?
  Roddy: why not? I will let you know later if I can go this Sat
  Sheri: ok! 
target: Sheri went ice swimming with her friend and wants to do it again. Eileen wouldn't dare but wants to have a look. Roddy will let them know.
