If I ever get married

If I ever get married, I want to build a box with our wedding date written on the outside. On the inside we would put two sealed love letters we wrote on why we fell in love and a glass of wine from the year we starting dating. If things ever get too hard and our love fades, we will open the box, drink the wine and read the letters we wrote to each other to remind us of how much our love means and for us to never give up.
