SO, I put my foot down here and there today -- I did it with a smile, but I did it, and got a small amount of cooperation as my reward. Which helps. It's going to be at least another week before the immediate stressors are past, and after that I'm taking a week off, just as soon as I can get away.
I'm not such an entitled person that I consistently feel undervalued. Sometimes I know my moods are a bid for some recognition and reassurance, and not much more. On the other hand, I can put up with bad behavior and demands from others for quite a while, before I snap. Being good natured most of the time doesn't guarantee understanding from others when you finally start acting like the "bossy boiler" as my son would say, but it keeps people from using you as a doormat. Which the best people will still do, if you make them think it's ok.
Enough for now.
