Friendship might be a theme. 14 - year - olds often place a high value on their friendships. Maybe this 'nibbi' has a group of friends and they go through various things together, like supporting each other through tough times at school or having fun adventures during the weekends.
I'm not sure specifically what the '14 years old nibbi story' is about as the term 'nibbi' is not a common one I'm familiar with. It could be a very personal or local story.
Another theme might be discovery. At 16, iyot could be discovering new things about themselves, like their talents or interests. It could also be about the discovery of the world around them, perhaps through new friendships or new places they visit. Also, the theme of identity might be present. As a 16 - year - old, iyot is likely in the process of figuring out who they are, and this could be a central part of the story.
One possible theme could be tradition. It might focus on how certain traditions were formed and maintained over time.
One possible theme could be the passage of time. An old lady has lived through many years, and the story might explore how time has changed her and the world around her.
One possible theme could be growth. At 12 years old, a child is growing, and their feet are also growing. So the story could be about the challenges of outgrowing shoes or the discomfort that comes with the physical changes in the feet.
One possible theme could be family. Since it's about old dads, it may focus on their family relationships, like their bond with their children and grandchildren.
One possible theme could be love. Maybe he'll talk about his first love, or the love he has for his family and friends.
One possible theme could be patience. If the old lady is constantly dealing with the fly, it might show how she has to be patient in the face of annoyance. Another theme could be the coexistence of different beings. If she doesn't try to kill the fly but rather coexists with it, it could be about harmony in nature.
A theme of celebration is also likely. Peaches are often associated with bounty and good times, and brandy can be a drink for toasting. So, perhaps the story is about celebrations over the years.
