You can't understand the feeling unless you've been in it and it feels different every time. When I was in my early 20s, I put down my beloved horse I had since I was 12 after he had a sudden stomach problem. I spent days in bed crying and googled "can you be dehydrated from crying". In my early 30s just when our son was born, I put down my cat and felt a different kind of grief from my sweet simple companion who had traveled across the country and back with me, a kitten I bottle fed at a few weeks old and had until her late teens.
And then there was Marshall.
