Thanks for taking an interest in my situation and for the compliment, I appreciate that very much.
As for our S's not saying "thank you," I have another idea about why they do not say it. I think they are so caught up in their storm that they cannot address our most basic needs. I think they may not see they are not addressing our needs. Given that, they certainly do not think of common politeness. My H will only sporadically say thank you to me now and it is very uncharacteristic for him.
I say this because I think the LBS has to be vigilant in maintaining as much PMA as possible. I am not suggesting to be Pollyanna about everything and make excuses for all manner of bad behavior. Rather, I am saying find positives when and where you can, and dismiss little negatives because they sap one's energy. Not that you seem to be making a big deal of this issue, it just struck me that it was a good time to give you this suggestion.
You sound grounded which is good and not easy to accomplish during all of this.
