When I go to DocJohn's chat, I usually don't say "hi" to everyone that comes in. Since there are so many people, if everyone said hi to me, or anyone else as they came in, I think it would be distracting!? I'm sorry if I seemed rude to anyone, but I also don't think, in THAT chat, that all the people (sometimes 20+) should respsond hi back to everyone that comes on. I really don't mean to be rude, but I guess I feel in that chat that it's more important to let Doc answer questions and others ask. (I guess I feel like I shouldn't just pop into the room with a big "hi" when others are conversing, maybe I relate it to real life?)
IDK, this is just my opinion for Doc John's chat.
