Fingernails - Exit-13

Fingernails subside between my teeth,

To help me cope with stress and grief

My fingernails could use some salt!

Yet this calcium treat won’t come to a halt.

I’ve chewed my fingers red and sore,

Now I’m jonsin' and need some more.

An ounce of fingernails would be looking good,

I’d chew on yours if I could!!!
