text: Cam: Any plans for Monday?
  Sam: Yes. I'm busy.
  Cam: Now or Monday?
  Sam: Both.
  Cam: When are you free then?
  Sam: I'd have to check my diary but I'm fairly sure I'm busy next week.
  Cam: What about the week after?
  Sam: I will check but the diary is pretty full at the moment.
  Cam: It would be nice to catch up one day.
  Cam: Do you know when you're not busy?
  Sam: No. But if I have some free time I will let you know.
  Cam: That doesn't sound very promising. LOL
  Sam: I know it doesn't and I'm sorry.
  Cam: It's been ages since we last caught up.
  Sam: It's also been a dead busy time for me hence I haven't been social at all.
  Cam: So, it's not just me that you don't have the time for? LOL
  Sam: No, not just you. 
  Sam: I haven't had the time to catch up on any of my chores let alone catch up with friends.
  Cam: No probs. I'll check back with you in a couple of days and see if you have any spare time.
  Sam: OK
target: Cam wants to catch up with Sam. Sam is very busy now and next week too. She will let Cam know if she has some spare time to meet.
