You will quite often see on this board that a person doesn't like a name because of a bad association, i.e., they knew someone of that name whom they either disliked, or who had some undesirable quality or qualities. It's common. Think of a name that you love, and I guarantee you that someone somewhere dislikes it because of a bad association. I've seen it here about my daughter's name,
Victoria: "Every
Victoria I've known has been a bitch", or "I like it despite the fact that I've never known a nice one", LOL. (My daughter is not a bitch and she's very nice.) There are all sorts of reasons that people dislike names and there is no name that everyone likes. So my advice is to keep on hating
Katie and don't worry about it.
