Sometimes being a writer is worse than being Charlie Brown. Not only don't you get invitations to parties, but sometimes you get a specific request to stay the hell away from their party, otherwise known as a rejection letter.
Charlie Brown once said, nothing echoes like an empty mailbox. That's not true. Nothing echoes like a form letter rejection in your otherwise empty mailbox, unless it is a form rejection accompanied by a solicitation to subscribe to the magazine that has just rejected your work.
