Two brothers have been sending one another the same birthday card almost every year since one of them first sent it to the other.
Ron and Jeff began the tradition and now, in 2015, it's still going strong.
They're basically doing what the card says and recycling it but - aww!
They've probably saved an entire forest in birthday cards by reusing it. Also, it's kind of amazing that the card lasted that long.
Have you any traditions with your siblings that have spanned years? Other than, you know, bickering every time you meet?
