text: Isabel: hey, you think you would make in on saturday or its better to meet next weekend?
  Alice: as I told you - I'm free on saturday and I can come but I don't have to
  Isabel: that's not the point
  Alice: I know ;)
  Alice: I didn't know Kate was not coming
  Alice: I must have missed that
  Isabel: yeah, she's away all weekend
  Isabel: so I was thinking maybe we should meet some other time
  Isabel: Beth is sick and Lily doesn't know yet
  Alice: I see
  Alice: I think I'm going to go out anyway so just let me know if anyone else confirms
  Alice: or let's just cancel it
  Isabel: how about next weekend?
  Alice: it's Jimmy's birthday remember?
  Isabel: shit I forgot!
  Isabel: ok... and 16th?
  Alice: ok for me
  Isabel: are you going to be at Jimmy's
  Alice: I don't think so I have classes
  Isabel: what time do you finish?
  Alice: 8,30 pl
  Alice: 8,30 pm
  Alice: it will be over before I get there
  Isabel: ok so I'll tell the girls 16th Jan
  Alice: ok. perfect.
target: Isabel and Alice decide not to meet this Saturday, since neither Kate nor Beth or Lily will be coming. They cannot make it next weekend, as it is Jimmy's birthday. Alice has classes till 8:30 on that evening and will not come to his place. Isabel will tell the girls they meet on January 16th.
