This is how I imagine a grand gesture happening. To me this is a gesture that shows real love. The realization that the person you are interested is not perfect, you have always known this and you still love that person no matter what. Their is something that draws you to that person like a bond that you have with no one but that person.
I believe that we are on any level can show love. Some people want love to be all crisp and clear, and not everyone can show that kind of love.
