'Gaeth a wyrd saw hio scel!' The Anglo-Saxon for 'Fate goes ever as it must.' Basically, shit happens. Or, oh well. Or (as we say in our household), it's just a thing. This can apply to the house falling down in an earthquake, dropping one's bread butter-side down on the carpet (sigh) or having Comcast's achingly slow interface infuriate me to the point of hurling the remote at the buttery spot on the carpet.
It's just a thing.
