My wife and I love going to national parks and trying to fill our “passport” (the official little Blue book) with all the stamps. We recently went to the US Virgin Islands and visited the park, collecting a beautiful sticker instead of the stamp. When we got home I found the wax paper for the sticker which was missing and assumed my wife had put it on one of her books or something. “We got the stamp [rather plain looking thing] on a piece of paper I thought you would put that in the passport. Days later I was flipping through the passport to put the stamped paper in there and found that my lovely wife put the sticker in the spot for USVI. :)
