I feel like that sometimes. But then I think it is good training, to practice expressing what you think, esp here. People are less judgmental or try to be. Most of us are moody/not consistent with how we feel; can be sweet and nice one day, cutting another day, because we are in pain, distressed. Because of that, I think moodiness is not judged so much here and is understood. I tend to judge people as being courageous, if they write something goofy, or very personal, or are exuberant one day, down in the dumps the next.
Not that my opinion should matter a damn.
