A little annoyance in the writer’s life is good for the soul (not). Like you’re expecting an overwhelmingly positive reply, as you think, almost beyond a doubt, you are going to get the publication slot. But you don’t. It just seemed that way. It’s like a trick played on you, but you’ve been self-deluded. A wake-up call in many ways, but not a fully soul-destroying one. A writer just keeps on going, nevertheless, and processes the “trick” played on you by someone you trusted. Then, you start over again, perhaps a little more guarded next time.
