One possible theme could be family. Grandmothers are often important figures in family units, so the novels might explore family dynamics, love within the family, and the influence of grandmothers on family members.
I'm sorry, I'm not very familiar with 'the grandmothers four short novels'. There could be many works with such a name. Maybe it's a relatively unknown or a very specific collection within a certain literary circle.
In 'The Grandmothers: Four Short Novels' by Doris Lessing, we can expect her characteristic in - depth exploration of human nature. The four short novels may each focus on a particular aspect of the grandmothers' lives. For example, one might deal with a grandmother's unfulfilled dreams and how it affects her relationship with her family. Another could be about a grandmother's struggle to adapt to modern times while still holding onto traditional values. Through these stories, Lessing may be aiming to show the multi - faceted nature of the female experience within the family structure.
A theme might also be the passage of time and its impact on the grandmothers and their families. As time passes, the grandmothers age, and the family structure changes. The stories could be about how they adapt to these changes, whether it's dealing with new family members or the loss of old ones.
Most likely the narrator and the grandmother are the main characters. The narrator is the one who is making the visit, and the grandmother is the focus of the visit.
Since I haven't read 'the two grandmothers full short story', it's hard to say exactly. However, given the title, we can assume that the two grandmothers are the main focus. There might also be other characters like family members (their children, grandchildren) or neighbors who play important roles in the story in relation to the grandmothers.
Well, it could be about cultural traditions. In many cultures, visiting grandparents is an important part of family life. So perhaps the story gives insights into some specific traditions during such visits, like special foods or family rituals.
Some grandmothers have big stories of traveling. They might have journeyed to far - off places, perhaps on pilgrimages or to visit relatives in other countries. These travels could have broadened their horizons and given them unique experiences that they can share with their grandchildren, inspiring them to be more adventurous and open - minded.
Since it's not clear if there are specific novels focused on grandmothers, but generally in his works, if there were grandmother - like figures, they might be sources of wisdom. They could be keepers of old stories and traditions in the fantasy worlds he creates.
