Q1. I saw this dialogue in a book:
A: "Mind if I see your notebook?"
In this context, "Sure" was used to mean "I don't mind, go ahead." Right? But in other contexts, "Sure" means "Of course", "Yes", right? So in the dialogue, isn't the "Sure" changed to "Sure not(?)" or "Of course not"? In other words, why do you use 'Sure' as a meaning of permission in the context of the dialogue above?
Q2. "Would you mind opening the window?" means "Would you mind your(or you) opening the window",or "Will you open the window for me", right?
But can the sentence be also used to mean "Would you mind my(or me) opening the window",or "Do you mind if I open the window"?
