I learned a lesson at the Cleveland Zoo, which was that if you bring up that fact that koalas have high rates of chlamydia while you’re at the zoo looking at some adorable koalas, people will accuse you of being a Debbie Downer.
Because no one wants to think of very cute koalas having decidedly uncute chlamydia. You might think you’re just sharing a fun fact and showing off how much knowledge you have about koalas but what you’re apparently doing is making people feel sad.
