James adopted a phrase a few years back to deal with my infrequent bouts of temperment changes. Ahem. "Don't poke the bear", he'd warn himself or anyone else within hearing range. That would mean that I was in a less than jovial mood and one should be slightly wary and avoid being stupid.
Surprisingly, that's easier said than done.
A few weeks ago, I asked him if it was difficult living with my "adjustments in mood". He paused for a moment and then came up with this response (this is pretty much verbatim):
"It's like.. oh...running up a mountain hillside, singing and dancing. And then blamo...you run into Nazis."
I'll skip the conversation that followed.
