Grod feeling peaceful in communicating with people is better than isolating yourself each time you get hostile and over react. If someone can't make an effort to discipline themself in this area going outside won't change their weaknesses. Soon as they come back to reply and felt hostility they would have to leave again soon as they read it and nothing would be solved they wouldn't improve themself at all. You have never thought about progressing yourself perhaps so you can't understand why it's not such a good idea to keep avoiding your own anger.
