Who are you?

So I understand the point of blogging is to put your thoughts out there for the "world" to read. But I really thought I could count my readers on one, or two hands. All the comments left are from people I know. So I got a comment from "Kelli" on my marathon training, but I can not think of one "Kelli" I know, so I wonder, who are you? Yes, it is just completely out of curiosity. You see, I am also Caller-Id Dependent. I know it is a condition..... Anyway, I guess I am just curious how this mysterious reader found my blog? Through a friend through a friend? Or just by happenstance. Anyway Mysterious Kelli, leave me a comment, and if you prefer, I will just delete it after I read it! Thanks for reading anyway, and your kind words! Oh, and I already tried to click on "Kelli" to read the profile, but it is not active for public viewing... thus the mystery......
