This delightful gift isn’t just for the happy couple who has some scandalous dirt to bury. It’s a fun activity now, and will be twice as meaningful in a couple decades. They’ll fill it with romantic keepsakes and cherished reminders of time spent together, then bury it in the ground. If they can remember where they put it, they can come back when they’re old and gray to dig it up. What could be more romantic than that?
