In lots of stories the mom eventually takes the bully's side in relation to her son. With her initial motherly feelings, unable to see anything negative in her son, she more or less gradually adopts the bully's view of the son. Some even joining the bully in humiliating and bullying the son, to a greater or lesser degree. And I was wondering, what could be a close to realistic motivation for the mother to do this. Besides the sexual attraction to - and desire to please - the bully.
One motivation could be frustration with her own parenting. That is, she sees her son developing characteristics that she doesn't like, that he is self centered, whiney, conceited and so on. She may have seen this developing for some time, unable to break from the all-accepting mom-role. And so, getting seduced by the bully opens up a door to accept those feelings.
Would be interesting to hear your thoughts about this. Also any other ideas for her motivations. Any real life experiences?
