Hi Dr. Bob...
I tend to not be quite so strung about things like Gabby. If he wants to post, I just say, let him. I've even responded nicely a couple of times.
It seems to me, for what it may be worth, and after some hard consideration, that if you treat someone as if you have higher than normal expectations of them (at least n their eyes), you will either get that response or they will go away.
In Gary's case, if he wants to go through here being nice and normal, I'll respond, and don't see any reason not to. Bottom line is that the only things in life that bother you are the things that you let bother you. Gary, Dave Simmons, and I had a set too on this forum earlier on. It left a bad taste in my mouth, and cut off someone that I had formerly considered to be a friend and not given to the kindergarten push and shove tactic. I may have cleared the air, as it were, but it didn't leave me feeling so good about myself, and my place in the arts. And thus, I go a lot lower key than I used to was.
The more that you post things that slap on Gary, the more he will make your life miserable. Actually, he was helpful to me in one of his last posts. And I just don't see the need for all the animosity. It hurts no one but me, and it rearranges nothing in the universe.
I probably will only use the ignore button on Nicholas, and only then when he is "wienying" (A word I just made up and only used in gest, Nick!!!l LOL??? )
