It's not ethical at all. Mom is a family member, and the relationship is based on natural family bonds, not something to be 'trained' in an improper way. Such an idea goes against the norms of healthy family relationships and basic moral principles.
One could write a story about making mom 'mine' in the sense of having a really close and unique bond. For example, a child might work hard to win a school competition just to make mom proud. It could be a story of how the child overcomes difficulties and in the end, has a beautiful moment with mom that cements their special relationship.
In a 'Making Mom Mine' story, perhaps a young girl saves up her pocket money to buy her mom a beautiful scarf. She then writes a heartfelt note saying how much she loves her mom and how she wants to always make her happy. This simple act of love makes mom feel truly special and shows the strong bond between them.
Making mom mine could be about learning from her wisdom. Mom has so much life experience. For instance, if mom is good at gardening, a child can learn from her how to plant and take care of plants. This shared activity can strengthen their bond.
I remember when my best friend's mom helped me prepare for a big speech I had to give at school. She listened to me practice over and over, gave me great advice on how to project my voice and calm my nerves. Thanks to her, I did really well. Her selfless act of helping me out is a story that always warms my heart.
Well, my best friend's mom once drove all night to pick us up from a music festival when we missed our ride. She didn't even complain. She just wanted to make sure we were safe. It showed how much she cared about us, not just her own child but also me as her son's best friend.
There could be several reasons. One possibility is that they are in some kind of trouble themselves and think blackmailing the mom can solve their problems. For example, they might have debts they need to pay off. Another reason could be that they are just bad - natured kids. They might enjoy having power over someone and see blackmail as a way to get that power. Or perhaps they have some secrets that they don't want the son to know and they are using blackmail to keep the mom quiet about those secrets.
Maybe they volunteered at a community garden. The mom showed the kids how to plant seeds, and the son and his friends watered the plants and pulled out weeds.
