If you are that shy, you are gonna have a hard time. What makes you think she would be interested in you without knowing you?
Many shy guys make the mistake of waiting for someone to be interested in them first, and then they move forward.
This almost never happens, because unless you are a really stunningly handsome and/or talented individual, girls won't
take the initiative to approach you. Girls are terribly insecure, so even if they thought you are cool, they might not approach you.
Think of it this way... you are in the worst possible position when you are shy and don't make a move. It can't get any worse.
Even if she rejected you, at least you know you tried and you should feel good. I just never understood why shy guys are so
uptight about their ego and their fear of being rejected. Makes no sense to me.
