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. 
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.
