Tell her that your friend only has a "floppy", and that you have "a real big and fast hard drive".
She wont even look at him again
Ok,enough of the jokes i guess.
Tell her how you feel.
I also want to know if your "friend" knows how you feel about her. If he does,and he goes after her,then he is no real friend at all.
You need to get this out in the open before some real feelings get hurt.
I wish you all the best.
