We did not meet this anniversary before my DH died but while he was alive we gave each other "community property" presents: one year gave each other 1/2 a stereo; another year it was 1/2 a new patio. Other gifts included halves of new floorings, underground sprinkler system, hot tub, etc. We enjoyed our "presents" so much and oh, I miss him.
Congratulations on your anniversary!
