Humans are the only animals that have children on purpose, keep in touch (or don't), care about birthdays, waste and lose time, brush their teeth, feel nostalgia, scrub stains, have religions and political parties and laws, wear keepsakes, apologize years after an offense, whisper, fear themselves, interpret dreams, hide their genitalia, shave, bury time capsules, and can choose not to eat something for reasons of conscience. The justifications for eating animals and for not eating them are often identical: we are not them.
