Wouldn't a secret admirer be.. well.. secret?
Secret admirers would be too shy/afraid to present themselves to you, so if they did.. they won't be secret anymore. And here.. is my obvious logic >>
So.. no one would ever walk up to me and tell me "I like you.. alot" Because well, I'm just..this average guy, nothing really to look up to or admire. Not much of a looker either. So if a girl walked up to me and told me that she had a crush on me, my response would be;
"*blushes slightly*... Hi."
Oh, and if it's a stalker. Well, let's just say, that I can stalk my own stalkers :3
