The cantankerous fib

Oh

my!

Am I

cantanker-

ous today. What louse

did walk across my liver?

– Leonard Blumfeld

And now to the explanatory part...
When someone is in a bad mood in Germany, one may ask "Was ist denn dem für eine Laus über die Leber gelaufen?" ("What louse did walk across his liver?") – so much for where that second part came from.
And what louse was it that walked across my liver? Mostly myself, I have to admit. I'm working hard on thinking of how to improve and avoid the potholes I've been stepping into in the future. As a first step, I shaved off the beard I'd been proudly wearing since about 1976. Now if that ain't a good or even significant start!
