  Sam: Hello Penny, with pleasure. Can you bring some sweeties for dessert. Are you going to the museum on friday?
  Penny: thanks et sorry no museum for me this time
  Penny: are you free for a sparking drink tomorrow evening?
  Sam: sorry, we're already invited. Another time. 
  Penny: we'll meet on saturday anyway
  Sam: Hi Penny, i haven't see your name on the list for the teens's activities  on saturday - before the party - Do you want me to give a lift to your son?
  Penny: oh, great , i was on the point of asking you, because i don't have the car on saturday. What time are you expecting him?
  Sam: 9.15 am, as I have first to go and pick up Herman to a friend
  Penny: finally i've got the car. Do you want me to go and pick up some other kids. Or bring them back home?
  Sam: No thanks, i'll manage
  Penny: Thanks a lot
  Sam: I'm sorry to ask you this, but could you move the party to some other date, my other guests are not available on saturday! Sorry sorry, but would it be ok for you in two weeks?
  Penny: don't worry, it' s ok for us. I'll note it right now
  Sam: Thanks so much
  Penny: by the way how was the museum this morning?
  Sam: very interesting. But our guide was such a pain
  Penny: really?
  Sam: yes she couldn't speak clearly and his german wasn't so good. So we all get bored, and wandered around looking by ourselves
  Penny: too bad
  Sam: luckily we had lunch in a very cosy restaurant with the girls.
  Penny: oh nice. 
target: Penny will come to Sam's party. Sam will go to the museum on Friday. Penny won't. Sam will give a lift to Penny's son. Penny will move her party by two weeks at Sam's request. Sam's guide on the museum tour was hard to understand. Sam had lunch at a nice restaurant later.
