One of the best ways to ask the woman of your dreams to spend the rest of your lives together is to take her to a nice, quiet, fancy restaurant...this will take a little bit of effort on your part, but the result is well worth it...what you need to do is go to the restaurant a few days prior to your big dinner, and tell them what you are planning on doing (that way, everything should go smoothly)...while at dinner, give her present that is beautifully wrapped...when unwrapped, she will notice that is a tiny little "lock box"...make her sit through the entire dinner, and when the waiter comes to bring the desert to the table (which you have already planned out to be "Key Lime Pie), have the restaurant staff put the key that opens that "lock box" on the top of her desert...when she gets the box open, get down on a knee in front of her, and tell her how much she truly means to you...
