I think the times are different. This from the deep meaning is a conflict of values, the old man in the era and now people face things are different, for the old man this is hurtful, but for the majority of young people, it is very normal.
Cosplay is just a personal hobby.
Obviously, the elderly take dressing oddly as a bad taste, she can't understand or accept these new trendy things, people are a kind of stupid animal, will instinctively attack or escape from the unknown things.
The old woman's words against the girl have resulted in libel, a personal attack on her (saying that the girl is a prodigal and doesn't do her job), making a big deal out of nothing (believing that her granddaughter doesn't do well in her studies because the girls go cosplaying), and bullying (the girl was silent the whole time, but of course it could be that the girl doesn't want to waste her time and breath on it).
Putting her heart in the right place, the old woman obviously didn't do it, if she was square dancing, did she ever think about causing trouble and distress to others? Is it also possible to say that my grandma does not even cook or do her chores because of your square dancing?
It's no wonder her granddaughter got bad grades.
If it was a boy or a couple of boys (or parents) tagging along, would she have dared to be so arrogant as to bully two little girls? Most of these things in society are these people bullying mothers and daughters (like giving up their seats) or two or three regular girls. And rarely against a male/female counterpart or multiple males. Imagine if this
old woman was confronted with a couple of physically strong male cosplayers dressed in relatively grotesque outfits, would she still dare to dislike them? It's human nature to bully and fear evil, and the scary thing is that you don't know you're doing it.
This society is too preoccupied with morality, but a normal society is built on a sound legal system. The girl's dress and mannerisms did not violate the law and did not cause trouble or distress to others. The law does not prohibit things, people have the right to do or not to do. For example, the subway bus seat or not is also
This, even if you do not let the seat, there is no violation of the law, morality, never override the law.
