The way Oscar Wilde used Algernon’s attitude to poke fun at society’s traditional rules of behavior is:

The reasons behind this answer are that in the first place the story takes place in a context that idealized and expected people to defend his family even if what people said about them was the truth.

As a result, most of the relationships are becoming tense. People have been stuck up in the attic with each other for a very long period of time, and they are growing restless.
