Elizabeth Bennet has muddy shoes
In Pride and Prejudice, Lizzie walks to Netherfield to visit her sick sister (which sounds exhausting, to be honest), and she gets mud on her shoes and the hem of her dress to boot. Everyone is scandalized.
Now you may be asking: what’s wrong with muddy shoes? What isn’t wrong with muddy shoes? Muddy shoes are a character flaw. Muddy shoes are everything that’s wrong with society. Muddy shoes are what killed the Archduke Franz Ferdinand and started World War I.
