Thanks for your comment Lydia. After I read your post I took some time to think about what was bothering me about this person. Then I realized that he had refused to tell me his last name when I asked him. For some reason, this did not set off any alarm when he told me the first time. I just thought it was odd. But it is not just odd. It was a warning sign. I am lucky my system protected me in the way that I did.
