Human emotion cannot be traded
When I was young my mom frequently read “The Man Who Kept His Heart In A Bucket” aloud to me. This book is about a guy who gets hurt by a relationship and resolves to stop the pain by physically taking out his heart and sticking it in a bucket to keep it safe. I got distracted by the fact that this lumbering automaton was somehow living with vital organs outside his body, and I didn’t really learn the book’s lesson.
