See, when I just read the title, I was thinking of the Sex and the City episode where Carrie attends a shower where all the guests had to remove their shoes, and someone else walked away with her $400 high heels.
But, a pair of crocs are just plain old comfy, not expensive, no excuse that you cannot get your own pair, regular shoes!
So, Aunt Fern is a few fronds short of a plant, and I would have to use the "No." as a complete sentence, and repeat ad nauseam.
(I have a few of the old "ugly" crocs and the newer Mary Jane sandals and regular sandals, that are quite cute, but...not once has someone wanted to wear them fresh off my feet!
