Error messageDeprecated function: array_key_exists(): Using array_key_exists() on objects is deprecated. Use isset() or property_exists() instead in Drupal\Core\Controller\ArgumentResolver\RawParameterValueResolver->supports() (line 18 of core/lib/Drupal/Core/Controller/ArgumentResolver/RawParameterValueResolver.php).
A few years ago, during the bedraggled final tatters of our relationship, my ex-partner and I were out walking our dog when we got into yet another heated argument. I can’t even remember now what we were disagreeing about, but as he asserted his view I asked, ‘But how do you know that’s actually the case?’
He replied, angrily and brim-full of conviction: “I know that’s how it is, because I AM RIGHT!”
