On July 5, 2018, you wrote an email to Karl, but he never responded. His full name is Karl-Hans Frimmel and he is the curator of the Animal Sound Archive. You still don't know what the main agency of The Animal Sound Archive is, but you have drawn the conclusion that it is an audio surveillance system that operates in remote areas all over the world.
You had written to Karl because you know that he keeps the recorders in his office, and you want to get into his office again. You want to gently touch the metal surfaces, you want to press the buttons, you want to smell the inputs and the outputs, you want to hold them in your arms and speak softly, in German, you want to moan, you want to cry and scream, you want to let your voice be sucked out of your throat until you have nothing left to say.
You never revealed your true intentions to Karl. Perhaps this is why he never responded. He could sense that you weren't honest, that there was something... queer hiding behind the formal language of your email.
