Wait, she said it's the first time somebody borrowed those books, which means this is the first time she did this, but this dude hears the rumor and comes here. My lord, why do I get the feeling she set it up so that he would come and ask.

Is even possible someone just started the rumor, she heard it and what she said at the start was to confirm if the guy was trying to do that.
Maybe it wasn't even about her but another librarian or her predecessor, after all.
