Hi Brett. I suspect that it's not a matter of copying your story, but like you said, perhaps your story was a reminder or inspiration about a topic he had been thinking of covering. Anther possibility might be that you were BOTH inspired by whoever wrote the content that you guys got your research from. It happens consciously and subconsciously with ideas, but of course, there's no excuse for outright plagiarism. But as for the topics we write about, there is rarely anything new under the sun. Nice of you to recognize that imitation is a form of flattery, if that is in fact the case :-)
