I've just had one of those cringing Homer Simpson "D'oh!" moments.
I get a phone call first thing this morning, and we have the usual small talk; he asks how I'm doing, and I give my usual early morning weary "Uh... I'm alive", to which he chuckles sportingly.
I say 'sportingly', because no sooner have we finished the conversation and put the phone down, I remember his comment about it being "his first day back at work" - after compassionate leave for a family bereavement... D'OH!
I am such a jerk. I really should stop watching House. He's a bad influence.
