Maybe the friend is jealous of the mom's life. For example, if the mom has a happy family or a successful career, the friend might feel envious and try to gain some advantage over her through blackmail.
It's really not common at all. Spanking by anyone other than your own parents is quite rare. Friend's moms usually would just talk to the child, call their own parents, or use other methods to correct behavior. For example, they might make the child sit quietly for a while or do a small chore as a punishment instead of spanking.
Well, my friend's mom is a fitness enthusiast. She organizes fitness sessions in their backyard sometimes. One day, she invited me and some other friends to join. She taught us some new yoga poses and told us how fitness has been an important part of her life for years. It was a hot (inspirational) story as she motivated us to take care of our bodies better.
Once my friend's mom was a volunteer at a local animal shelter. She would often bring home stray animals to nurse them back to health. One day, she found a little kitten with a broken leg. She took it in, got it proper medical treatment, and within weeks, the kitten was running around happily. It was so inspiring to see how much she cared for those animals.
The sons' black friend could be a great artist. He might have shown the mom and sons his paintings which were inspired by his life experiences. This led to a deeper understanding of his creativity and emotions within the family.
I'm still not clear on what a'mom suck friend story' is supposed to be. But if we assume it's about a positive relationship between a mother and a friend, it could be a story where a mother befriends her child's friend's mother and they support each other, like sharing parenting tips and having playdates for the kids together.
My mom's friend took me to a park once. We fed the ducks and had a long walk. She told me about her travels around the world, which was really inspiring. It was a great day full of new experiences.
The most interesting thing was her collection of old books. She had a whole room filled with books from different eras. It was like a little library. Whenever we visited, she would show us some of the rare books and tell us stories about how she got them.
