Having stuff in common with someone is usually the cornerstone of friendships and romantic relationships. But who cares about the stuff you like? That's easy. Who doesn't like pizza, puppies and rock ‘n' roll? Sharing the same hatreds is a lot more important. Black olives, chocolate and coconuts and hipsters are all excellent things to hate-bond with someone over. If you have a special hate friend, then these hilarious birthday cards make an excellent hate-sharing gift.
