Just a few days after our wedding, my grandparents will be celebrating their 65th wedding anniversary. While I would like to honor them somehow, my mom thinks they should have a cake, and I don't agree. An easy way to do it would be to let them have a dance or walk in with an announcement, but they will not be walking in at all because my grandfather does not walk very well anymore. Anything involving walking or dancing wouldn't work. Does anyone have any ideas on how I can honor them?
