dont give her any gifts. You\'re not even going out with her!! And you dont know if she likes you or not.
If you dont have any contact with her, then you\'re going to have to call her. If she gets all freaky about how you got her number, just tell you looked her up. If she responds negatively to you calling her without her giving you her number, simply hang up on her and forget about her -- because if she likes you -- i seriously doubt you would get a negative response.
...and dont forget to ask her you when you call her. Ask to actually do something (movies, minigolf, whatever), dont just say \"will you go out with me?\"
