Like a splinter in your mind.

I sliced my fingernail in half on an apple peeler while trying to unjam a stuck kitchen drawer.

It didn't hurt. Just incredibly uncomfortable. Like nails on a chalkboard.

And even though the slash is only a sliver in width you would be amazed at how everything gets caught in it. It is like I have velcro wrapped around my finger.

I probably think about my fingernails once a month.

Now it is all I can think about.
