Robert: Look, I have French on Monday, English on Tuesday and German on Thursday.
SiElenka: You are so lucky! I have no French classes this week, but I have English classes on Wednesday.
Robert: What classes do you have next Friday?
SiElenka: I have German classes on Thursday with you and I am free on Friday.
Robert: Well, at least you don't have to go to the library on Saturdays.
SiElenka: You are right, I can go to the library on Friday and go to the gym on Saturday.
