Personally, I think it's unethical for them to trespass and leave a mess. They could have applied in advance for the right to use the dance room and made sure the room was well organized.
In real life, there are always some people who think that the public **** place is cleaned by the sanitation workers, and they will not take the responsibility of cleaning the public **** place. In fact, we can think of the problem in another way. If strangers come to a home and don't care about the opinion of the home owner. They are doing their own thing and leave with the feeling that they are not at fault.
The first solution: make amends
An apology is not indispensable, and the owner of the dance training room cares about the attitudes of the seven amazons, not about the facilities inside the room. If only each of them would take their respective responsibilities and restore the dance training room to its original state. In this way, the training room owner and the seven amahs will come to an agreement. The real situation was not the same as the ideal state, six of the amazons were not willing to stay and clean up the room, and only one was willing to take responsibility.
The second solution: public treatment
Since each side has its own argument, each side has its own reasoning, the two sides can take the legal route. The law is not concerned with human feelings and emotions, the law is aimed at the suspect and the matter. The suspect has been officially determined to have committed a crime, then the law will follow the detailed terms of the sentence. The nature of trespassing in a dance studio is slightly different from trespassing in another person's home, the former is more inclined to public **** premises or private company premises, while the latter is aimed at every family. Nevertheless, the dance training room responsible person should choose to defend their rights according to the law, every big mom can understand that the law does not tolerate.
Overall, we do not fail to understand the feelings of the seven amahs in search of a suitable venue, but the dance training room is not a public ****ing venue. What's more, they didn't make any advance reservations, and entering an unfamiliar place without authorization doesn't give them a pleasant mood. After the experience of the big moms, learn from their mistakes and don't ignore the common sense of the law.
