text: Wiktor: We're going to the swimming pool tomorrow - then sauna and dumpling restaurant, wanna join?
  Kacper: You could write all the details right away - when and what time. I was planning to clean our apartment, but your plan sounds better than cleaning :D
  Wiktor: 12:30 in swimming pool nearby our bus stop. After that dumplings. Take the slippers and two towels per person (sauna's requirement). And why you're not in bed yet:D?
  Kacper: Eh, it sounds tempting, but house won't clean itself 
  Wiktor: Oh, that's a pity :(. Maybe next time then, dumplings will wait. Enjoy your cleaning!
  Kacper: Thanks, maybe you'd like to help :)
  Kacper: Hello?
  Kacper: That was a joke!
  Wiktor: I know :D
target: Wiktor invites Kacper to join them tomorrow, when they go to the swimming pool, sauna and a dumpling restaurant afterwards. Kacper feels tempted but decides to clean their apartment, as planned.
