Oh my god.
Hurry up and call her, you might have blown it. She kissed you for christs sake. Is she a decent girl, does she go around kissing people for no reason?
My bet is that she liked you. Call her.
To love is to suffer. To avoid suffering, one must not love; but then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love; to be happy then is to suffer, but suffering makes one unhappy; therefore to be unhappy one must love or love to suffer or suffer from too much happiness. I hope you're getting this down.
