Lucas: Howard and Nancy are coming to visit me on Saturday
Lucas: how about you John? Wanna join us?
John: this Saturday?
Lucas: that's right, in the afternoon.
John: damnit. I want but I can't...
Lucas: Come on, why?
John: this Saturday I'm working until 5 p.m. and then I have an appointment at the dentist's
Lucas: oh my... looks like a busy and unpleasant time...
Lucas: I'm sorry for you, John
John: there certainly are things in life you cannot skip
John: but thanks a lot Luc, I appreciate that you invited me anyway :)
Lucas: no problem, you're my friend, bro :)
Lucas: hope you won't suffer too much at the dentist's
John: thanks!
John: don't worry, he's a real professional, I trust him
Lucas: good for you
John: yeah. Have fun on Saturday and say hello for me, please. Bye
Lucas: Thanks, I will! Bye
