"Just give her the D."
A red rose or white rose and a card asking her to be you're girl friend.
Give me her number and i'll ask her for you :)
Yeah that should help!, lol, didn't realise he was so young, just seen his age!, that makes his gf about the same age, oops! :O
good luck dude, just try and be confident, you are not the only shy person in the world. don't say "will you be my girlfriend?" just ask her if she would like to go to the cinema with you or something :)
