I just can't stop shaking my head at this.
I'm so sorry to hear that you were subjected to that...I'm sorry, but I'm not surprised. I'm not gonna say shoulda, woulda, coulda on this. It could have played out in a multitude of ways...both good bad, and hilariously funny but I'm sure imminently illegal as well. ;) I think that from what you wrote you handled it with a level of rational dignity I'm not sure I could have mustered. I applaud you for that...and I think ultimately what that P.O. said doesn't really matter in the grand scheme of things?
It's just a nother reinforcement that leaving the org was the right choice. It was also nice that those in attendance granted you condolences and sympathy that you rightfully deserved. Don't let that arse ruin the memory of your mother's memorial.
