8/ Miss Webber is very kind to Joseph, she seems to act as a mentor. We can understand how benevolent she is thanks to words like "she smiled". We can also deduce that she is not only teaching Joseph about writing but also about a meaningful topic, about something deeper in his life thanks to the quote "Yes,” I said, believing I did."; showing that he did not fully understand how deep that advice could be at the time. (78 words, sorry about that !)
For the others questions I'm not sure to understand; but at least you'll be safe for the eighth !
