Any chance at all you could avoid her? Looking for even the tiniest morsel that might be scraped from your plate (you like that visual, eh? -- into the garbage, compost... you pick!) Even as someone who -- just this morning!-- got pretty damn worked-up (and wrote a full page Rarr Rarr Rarr in marker intended for their windshield...then waited outside smoking, for if she came back, I was more than happy to deliver a sharper diatribe in person ), I'd probably advise not to. Giving them a good telling off in your mind? Oh yeah. But the good thing about in your mind is you control their reaction. And you are, but of course, victorious! And they are properly cowed by your totally justified righteous indignation. But in real life... they might well respond in a way that fries your bacon even more(!) And, I don't know about you, but for me, when I'm feeling explosive... that could go very badly. Worse than that, the rebound's more likely to affect you than her. I don't know, maybe it wouldn't go that way, but it tends to go that way in my universe...

Eventually, I usually get to the solution of thinking, "Damn b****!!! $%% ^&%%^^ doesn't deserve the time of day! Just see if I waste breath, let alone my time and energy on her! She doesn't deserve it (the honor )! Real estate in my head is out of her budget, that's for sure! She can just go %^&^ ^^$#(*@$#"!!!!! Etc. Except with much more swearing.

P.S. She didn't come back, and I opted not to leave the note. Oddly enough, the note was pretty civil. But the writing was large, bold, contained underlining and informed her of the ignorance of her false assumption. Teehee.
