Actually there is a second reason-- detachment. Last night I taught my acting class, and this is something I do extremely well. So I had a whole room full of people who were admiring me and appreciating what I was able to do for them. And even though I remembered W and my sitch while I was there in knowing that I would not be able to come home and share my triumphant experience, by the time I was done I was again "bulletproof".
I mean, it's more than pathetic what I had devolved into because of my reaction to this A. That wasn't me; that's not who I am. And who I am is someone who can look at this situation from a detached perspective and say "what a stupid thing to be happening!" and shrug, and shake my head in disbelief, and get on with my business.
