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
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.
