What really annoyed you today? (Patreon)

This afternoon, my banshee started a kitchen fire and then disappeared into thin air, shrieking all the way. Thankfully, I'm quite the pyro, so putting it out was not a real problem. Yet, cleaning up another's chaos does not really butter my parsnips, so I was rather miffed. What part of your day pushed you to the brink of wanting to poison someone's tea?
