the idea comes from the heart..
not every women has the same taste...
take her to the mall, walk past a jewelry store and pick a random ring and say hey this looks nice... LISTEN to what she says, she gona say its ok... should be more like this.. or i dont like it.. then be like

i like it or

its freaking $$$$$... or

and pull out a ringpop and say this is all i can afford
and just remember what she likes.. go back later
