I'm sort of in the same boat. I give talks maybe once a quarter and if it's a subject that I'm not comfortable with, I'll switch with someone saying I think I'm traveling on business that week. So, I try to do that early enough that if I happen to be there that night, I can say that the trip fell through at the last minute. So far, so good.
I can't bring myself to comment anymore. I used to try to make a comment that didn't bother me but the tone of the WT studies and CBS is so Obey the GB that I had a hard time doing that without resorting to childlike answers. But, no one has ever said a word to me about it.
They don't ask me to read, pray or carry mikes which is great since I don't want to do any of that.
