text: Tom: Hi! Have you by any chance been to Mary's party?
  Diana: Hi! The one yesterday? Why are you asking?
  Tom: Yes
  Diana: Yeah, I have
  Diana: Oh god, I haven't done something stupid...
  Tom: Hahaha, no, don't worry.
  Tom: I found your oyster card, thought you may be looking for it :)
  Diana: Thank you! I haven't yet, so you saved me a lot of stress, thank you!
  Tom: No problem. We've just begun to tidy the place up and it's been underneath the sofa
  Diana: I really don't know how to thank you. Maybe we can go for a coffee? :)
  Tom: It'd be nice :)
  Tom: But you really don't need to thank me, it's nothing.
  Diana: So are you free this evening? Just tell me when and where we can meet.
  Tom: Would O'Neils do?
  Diana: Sure :)
target: Diana got drunk at Mary's party yesterday and lost her Oyster card. Tom found it and Diana will take him to O'Neils as a thank you this evening.
