It could also be due to financial situations. If the family is tight on money and the mom blackmails the child into getting a part - time job to contribute, it's because of the overall family financial health. For instance, the mom might say that if the child doesn't get a job, they won't be able to afford the child's extracurricular activities.
One reason could be for the child's betterment. For example, if the mom blackmailed the child to practice an instrument, it might be because she wants the child to develop a talent.
Another reason could be out of frustration. Maybe the mom has been asking the child nicely to do something like helping with chores, but the child keeps ignoring. So she resorts to blackmail to get the job done.
Greed could be one reason. If the son is money - hungry and knows his mom has something to hide, he might blackmail her for financial gain.
One consequence could be a damaged relationship. For example, if a mom blackmailed her child into doing something they really didn't want to do, the child may grow to resent the mom. They might become distant and less likely to trust the mom in the future.
One reason could be jealousy. A person who is jealous of the wife's happy marriage or her status might try to blackmail her to create chaos in her life.
One reason could be a mistake the teacher made, like the wrong grading as in the previous example. Another could be some personal information or past event that the blackmailer got hold of, such as a teacher's past academic failure or an embarrassing photo from their youth.
One possible story could be that mom discovers some illegal activity by a group of people. They blackmail her to keep silent by tying her to the bed and threatening to harm the family if she tells anyone. However, mom manages to leave some clues for the family to figure out what's going on.
Well, perhaps the son has some financial problems and he blackmails his mom by threatening to expose a family secret that she has been keeping hidden. It could be something that would make the family look bad in the community, so she is forced to comply with his demands.
The blackmailer could face legal trouble. Blackmail is illegal in most places, so they might end up in jail or with a criminal record.
One reason could be a lack of emotional connection in her marriage. For example, if her husband is always busy at work and doesn't have time to talk to her about her feelings, she might seek that connection elsewhere.
One reason could be love. A mom might be submissive because she loves her children so much that she is willing to sacrifice her own wants. For example, she'll let them have the last piece of cake.
When it comes to safety issues, moms may spank. For example, if a child runs into the street without looking, the mom might spank to make sure the child understands how dangerous it was and never does it again. It's a way to quickly drive home the importance of safety.
