Well, I believe Edward the Confessor was the famous Anglo-Saxon historian.
I'm not sure but I believe it is because Sancho Panza will not receive any wages. But you may want to wait for someone who may have already answered this question or read the entire book, as english and literature aren't my strongest points.
After the car accident, the narrator believes that her mother is hurt.
Explanation:
The fear and relief that the narrator experiences after realizing that her mother is unharmed, is followed by her throwing the umbrella away.
This helps the reader know that the umbrella, and what it represents, is no longer important to the narrator.
With the events that happen during the time of the accident, the narrator realizes the extent to which she values her mother and that she doesn't need an umbrella that represents her earlier rejection of her mother.
