Extraordinary swings in mood sometimes come out of nowhere.  Or it could have been the election!

Either way, it demonstrates how we are moved by factors beyond our control, e.g. internal factors like thoughts/memories we do not choose and external factors like political/societal changes.  

We like to believe ourselves to be captains of our own ships, but we’re really just along for the ride.  Anyway, happy to hear that storm passed for you.
