Do I have a sign on my back?

Recently I was perusing the book and magazine aisle at the grocery store.   There I was, minding my own business, when this lady starts speaking to me while she looking through magazines.   After some initial chitchat she asks me if I know of the best diet pills for women.   I must have given her a funny look, because then she explained that she was looking quickly through magazine ads to see if she could find something about diet pills.   I suggested that she go on the Internet and do a search because that’s how I discovered new things myself.   Then she said she didn’t have a computer, so I told her there were free computers to use at the public library.   She thanked me for my time and off she went.   Maybe I just have a sign on my back that says ask me silly questions.
