I just received a rejection letter, and I'm not upset. I actually expected it since the story very loosely fit the criteria. Can't say I didn't try.
Getting the rejection actually made me happy. Why? It was a personal rejection; the editor showed that she had taken the time to read the story, by her comments, and hadn't simply rejected it because she was tired of reading the slush pile.
I was also was happy that she didn't just accept it because she's accepted my other work. That makes me feel great about the editor I'm working with.
