I know how you feel because I'm in a same situation as you, except that I'm shy and she's not. Starting a converstation is a good start so that at least she'll know that you show some interest in her. The problem with me though is that whenever I feel like talking to her, my feet suddenly feels like cement and I can't move. I hesitate. Then when I finally get close enough to talk to her...my mind just goes blank . Then I just sit back down not know what to do. I don't know what to say either unless she starts a conversation.
