text: Frank: Hi there! What are you up to this weekend?
  Maria: Hey! Not sure yet, any ideas?
  Frank: I don't have plans either, should we meet?
  Maria: Sure! How about Friday? I finish work earlier so we can meet for dinner, what do you think?
  Frank: Sorry, I can't on Friday - I have lectures ...
  Maria: No worries, what about Saturday? I have some stuff to do but I can be free in the evening.
  Frank: Let me check my diary ... Oh no! My mom's birthday party ... I totally forgot!
  Maria: Oops ... That doesn't sound good!
  Frank: Oh boy, I don't have a gift!
  Maria: Well, we can look for something together if you need help ...
  Frank: Are you sure you have time for that? 
  Maria: I can help you, of course, but only on Friday, as I said, I have some work to do on Saturday.
  Frank: Ok then, let's meet up after my lectures, is it ok with you?
  Maria: Ok, sounds good, where should we go?
  Frank: Let's go to the new shopping centre, they have all the shops I want to visit.
  Maria: Ok ... will 7pm be ok?
  Frank: Yes! Perfect!
  Maria: Great, see you then, I hope we will find a perfect gift!
  Frank: Me too! We don't really have another option! See you!
