Karin: No, she didn't. I forgot to ask about it as well. 

Damar: As I know, the books in the library can be borrowed for a week maximally.

Karin: I borrowed it three days ago.

Damar: It means, you borrowed it on Monday, November 11th, 2021.

Karin: That's right. Well, it's good to know that I still have four days to read this book.

Damar: But, you must return it on time.

Karin: I know that. Thanks for reminding me.

Damar: Once again, don't forget to return it on Monday, November 18th, 2021.

Karin: Don't worry about that.
