Friday poetry challenge: small annoyances

Here's the miscreant that caused all the trouble in my Volvo last week (read it here). This little bolt was flipping around the flywheel, making my car scream and clatter like the end of the world. My mechanic couldn't find a place where this loose bolt might belong, and there's not much point in taking the entire engine apart when it's running just fine right now. So we've decided to leave it alone and see what happens.

It astounds me that such an insignificant item could bring my car, my household, and my entire week to a screeching halt, but isn't that the way life works? Many small things can make big trouble: a pebble in your shoe, a microorganism in your breakfast egg, a missing bolt on a bridge. What else? Your challenge today is to make poetry out of the small things that make big trouble in your life. I'll start:

Bitty bolt, flywheel
flusterer, screech and clatter
til all systems stop.
