Take your lady out to dinner. Earlier that day arrange that 12 restarant hosts come up to your table all carring balloons and a single red rose to give to her. After all 12 have come by(within like a 3-4min. time period), and your lady is like "what the heck", give her a final pink rose symbolizing not only your love(12 roses) but also your friendship(pink rose) and then pop the question with all the old fashion sweet words!
