Some adults may feel extremely humiliated. They are no longer children and being spanked makes them feel as if their parents don't respect their adulthood. For example, they might become withdrawn and avoid family interactions for a while.
First of all, communication is key. If a parent catches something like a gay nanny teaching their child about acceptance of all sexual orientations, they should sit down and have a conversation with the nanny. They need to set boundaries if necessary, but also appreciate the positive aspects such as promoting inclusivity. For example, if the nanny is just showing the child that there are different kinds of families in the world through stories, it can be a good thing as long as it is age - appropriate.
If parents come across disturbing content in Descendants fanfiction, they should immediately stop watching it. They can also report the content to the platform where they found it if possible.
Parents can react with understanding. They should create an open environment where the teen feels comfortable to talk. For example, instead of getting angry immediately, they can listen to the teen's feelings and experiences.
Some parents laugh. They find it kind of funny and a sign that their baby is healthy and growing. They might take pictures (carefully, of course) to remember the moment.
Harry would probably be overjoyed at first. After all, he has always longed for his parents. He might start to look for ways to make it happen, like searching for magic spells or ancient artifacts that could bring his parents back.
Lily would probably be very warm and welcoming. She was known for her kindness. She might immediately take a liking to Ginny, seeing her as a strong - willed and intelligent young witch, much like herself. James, on the other hand, might be a bit more boisterous in his welcome. He could be impressed by Ginny's skills in Quidditch, if that comes up in the meeting, and would likely be glad that Harry has found such a remarkable girl.
She would be devastated. Hermione is a very emotional person deep down. She might isolate herself at first, not wanting to talk to anyone, even her closest friends like Harry and Ron. She'll probably go through a phase of denial, not believing that her parents are really gone.
At the start, Harry would be stunned. His whole life has been built on the idea of his parents being heroes. When he realizes they betrayed him, he would be heartbroken. He might go on a journey to find out the real motives behind their actions. Along the way, he could become bitter and vengeful. However, he might also find some inner strength and decide to rise above the betrayal. He could use it as a motivation to break free from the shadows of his parents and create his own path, but not without a great deal of emotional turmoil first.
