Family bond. It emphasizes the strong connection between a mother and son. No matter how old they get, they are still there for each other, which is a very important aspect of family relationships.
One possible theme could be family. It's about the relationship between a mother and son which is a fundamental part of family.
One possible theme could be family bonding. The act of the mom 'riding' with her son, whether it's on a vehicle or an animal, creates a shared experience that brings them closer together.
One possible theme could be protection. The son using his fists to protect his mom from harm, whether it's physical danger or from unkind people.
Well, possible themes might include cooperation. The son and his friend are working together, so that could be a central idea. Also, persuasion might be a theme, as they are 'forcing' the mom in some way, which probably involves trying to convince her of something. And there could be a theme of growth or change, perhaps the son and his friend learn something from their interaction with their mom, or the mom changes as a result of their actions.
The theme of family support could also be prominent. The mom driving her son to college is a physical act of support, and along the way, they can share emotional support as well, which is important for the son as he embarks on this new journey.
Another theme could be growth. Maybe the mom in the story grew as a person in 2017. She could have learned new skills, like cooking different cuisines for her family or taking up a new hobby which also benefited her family in some way. And this growth could be both personal and in terms of her role as a mother.
One possible theme could be struggle. A 16 - year - old mom has to struggle with many things like taking care of a baby when she is still a child herself.
Another issue is the son's own internal struggle. He might be confused about his identity at times. If his mom has feminized him in certain ways, he could be torn between the traditional male expectations he sees around him and the values his mom has instilled. For instance, if he's more empathetic like his mom taught him, but in a competitive male - dominated environment, he may wonder if he should suppress that side of himself.
One possible theme could be love and protection. A mother always loves and protects her son, and this could be a central part of the story.
