Perna, thank you for that, that makes so much sense...to think of it as communication, which is a positive thing. And to realize that when other people makes demands and I need to refuse (for my own sanity if nothing else) isn't nasty. I think the way I will view it from now on is they are asserting their need for immediate attention...I'm just asserting my own need in return that I can't go there at that precise moment.
And I like the examples you gave, they're very helpful in helping me to understand.
Thank you
