KF, I respect everyone's opinion re the cause(s) of PD. However, the more I read, the more I return to my own theory, a theory I've expounded on many times. Personally, I'm tired of the merry-go-round of promises that turn into sour pickles! I wonder when we will use our combined strength to say ENOUGH!
