How did u purpose ur wife or ur girlfriend or husband or bf?

I haven't propose yet, but in my mind, my proposal will be at a beautiful sun rise or sun set. I will keep a treasure box under the sand if it's on a beach, if it's on a hill, then i will put it at the back of my car. Then inside the treasure box, there will be a banquet of flowers, a vows, a master key to my house and photo album of the happy moment together. There will be another piece of clue, if she is willing to accept marriage, please proceed to find out where is the treasure. Of cos, it will be the wedding rings. If she agree, then she will easily find out where i keep the diamond ring...
