The annoying unicorn is someone you keep around because he or she is objectively and without a doubt, possessed of a rare, brilliant, and valuable talent or skill that you need.
Unfortunately, they are such difficult and unlikeable personalities, that it is actually physically painful when you’re forced to deal with them.
It’s like having a unicorn that destroys your furniture and ruins your rug. You would love to get rid of the beast. But you can’t, because it’s a unicorn!
Hence the dilemma.
Next week I will write about the Disgusting Fairy, and the Farting Mermaid.
