Most of the time my glass is more than half full. Sometimes I may not be happy with what is IN my glass, but that is not a problem either. lol I love the PDA for those days when things don't go well and I can "share" with my friends on the QB who care to read my nag-nag.
Now I do believe that it is OK to offer valid concerns and ctiticism but it needs to be constructive, and it should not become a feeding frenzy at the cutting table. (How do you like that analogy? teehehe)
For the most part, this is still a happy group. Sometimes I hear that someone has backed off or even jumped ship because someone else has gotten under their skin. I must admit that I have been pretty oblivious to those undercurrents and I think it is sad when it happens.
