I met him head on this time, and told him that if he really believed that then we had some serious discussing to do, and if he didn't believe it could he please tell me what he was really feeling. I further explained that I simply couldn't do his irregular hours, and that it was angering me both at him and at mayself for failing to respond to his wee hour overtures. If he was feeling amorous, I certainly wasn't picking up on the clues, and if he had serious matters to discuss, I'd appreciate it if he'd either discuss them when I was still at least semi-comotose or, failing that, to let me know up front what the problem was so that I'd have reason to wake up instead of hit a slow fume.
The Prof was cool about it. No fight, no flip remarks (once he realized I was serious and not in the mood for flip remarks), no witty comebacks or "well you did this so I did that" defenses. Again, I underestimate him. I should be ashamed of myself.
I should get into the habit of saying I'm annoyed and talking it out on the spot rather than waiting. Mea culpa.
