Here is a great idea I heard from one of my brides. Instead of saving a year old piece of freezer burnt wedding cake for your first anniversary, try this:
Grab a bottle of Champagne (like the kind you will use on your wedding day), and your wedding day champagne flutes if you have them. Buy two small notebooks and write down a few things about your future spouse, and tuck them all away in a box in your closet. On your 1 year anniversary, you get to open the champagne and read each others notes. Buy another bottle of champagne, write new notes and do it again every year. This sounds like a great idea to me and in a few years you will have all these really wonderful reasons why you love your husband/wife.
