Go simple. Maybe a card or a little letter stating nothing sappy. Your wedding day did happen, and you ended up with some good memories from it. My BD was 6 days before our 15th anniversary. I bought a card and wrote in it " Happy 15th. Thank you for 15 years and 2 wonderful boys" and signed my name. She kept the card, something she rarely does. We went out to dinner as a family and created a few good memories.
