You know, I looked it up and there's no traditional gift for 41 years. Forty years, yeah, that's traditionally rubies and a party thrown by your youngest daughter. But for 41 years? Nothin'! Heck, most of the other sites skipped over years 41-44 and went right to 45.
Instead, they suggested a modern gift: land.
In the words of Dave Barry: I am not making this up.
However, since I am not rolling in the dough, my ability to gift you with a piece of land would be limited to shipping you some soil from my yard. Or else sending you a picture of some land.
Instead, please accept my warmest wishes for a healthy and happy 41st anniversary. May you have many more.
