why didn't griffin like to be friendly with Mrs. Hall
Answers
In the story we get to see that Mr. griffin was actually very cold, rude and distant towards Mrs. Hall.
During such a harsh winter, Mrs Hall did not actually expect any guest to turn up at her inn so when Griffin did come to stay, she wanted to be the best host possible.
But griffin did not want anyone to know about his past or what he was going to do next so he was very rude to Mrs Hall.
Griffin was in reality, a very indifferent person especially to Mrs.Hall.
His character progression is one of the best that can ever be seen, where he slowly has a change of heart and soon changes his outlook on the lady and comes to visit her inn, she was not expecting this, yet she tried to accommodate the man and made him comfortable to the best of her ability.
