  Zack: I'll think about that :-p
  Robert: If you find an hour or two in your diary, don't hesitate to contact me :-D The phone number same as ever.
  Zack: Rob, I'm going to sacrifice one whole evening for you. Maybe even the whole night. And you demand only 1 or 2 hrs? 
  Robert: How kind of you :-)
  Zack: We'll get back to that some time in December, ok? It's too soon to plan anyth.
  Robert: Sure. Good to know you still remember about us.
  Zack: Every year you do your utmost not to be forgotten, Rob, if you know what I mean. Till later :-)
  Robert: Cheers!
