Have you ever received an angry letter from a friend right out of the blue? It can really shake you up, especially when you're not really sure "what happened." Typically, friends send a letter like this when they feel they aren't being heard. If someone won't listen, it allows them to get out everything they are feeling. This is especially true if the friend talks over them or blows off their concerns.
People who receive a letter like this often feel like they don't know where the anger from their friend came from. As a result, they either shut down or yell back at them. Either way, it doesn't help solve the issue or get the heart of the problem. If you're thinking of sending a letter like this, I've got some advice.
