Shoenicorn 

Can also be spelled Shunicorn. It is a beautiful shoe you own. You cannot find its mate but it is too good to throw away. You will never wear it and it makes you sad.

Why do you have those beautiful single shoes on your shelf at work.

They are Shoenicorns and I am just thankful to be able to look at them
