Not A B or C

Before I became disillusioned with my writing course I had to write a short story as an assignent which I duly did. My tutor said that it was good and suitable for magazine A and that I should send it to them which I did. They didn't want it so I sent it to magazine B. They didn't want it either so just after Christmas I sent it to magazine C. This "good" story was returned to me again this week. I can't give it away.
