To make someone notice you

Declare mentally tree times in a row, with conviction, the following words:

"Deus auribus nostris audivimus"

while touching the shoulder or arm of the person you want to attract.
Then during the following 9 days, while being alone, read these words aloud, three times in a row, and three "Our Father" and three "Hail Mary".
The power of these prayers added to the three fold repetition (three being the number for achievement and perfection) is a very powerful magical combination.
