Why is it making fun of society at the time?

Scandal in High Society

Saki satirizes the bourgeois nature of Edwardian society in “Tobermory” by upending the ‘prim and proper’ portrayals of the upper class in order to reveal a scandalous underbelly. Saki points out the hypocrisy of the extreme class divisions premised on the superiority of the higher classes. He does this by granting Tobermory the skill to reveal the sordid scandals in which even the wealthiest were engaged.
