Kachemak Sea Otter, a 23-year-old sea otter who, despite having a cute little face and compact, huggable body, would have watched nonchalantly as you were brutally stabbed to death in front of her, then cracked open a clam on her tummy for breakfast (because her brain was not wired for empathy), died on Saturday at Shedd Aquarium in Chicago. It was sad in the knee-jerk way that something different is often described as "sad"; like when you say "I miss when these walls were painted yellow" but what you mean is "I remember when these walls were painted yellow and now they're different."
