JFT7 you know I have on occasion called folks down for gossiping, especially around newcomers or one of my sponsee's. I have been to a few meetings where gossip was the topic, learned a lot about the harm it can cause.
One thing that I was told and I have passed on to my sponsee's is that we have absolutely no control over what others think of us, but we do have control over what we think of our selfs. If we are doing the next right thing and we are doing our best people will notice, the gossips will gossip, but your actions will make their crap mute!
We know our own heart, we know the person we really are and that is what matters.
You know JFT7, if this is a discussion meeting then I would make sure I brought up gossip as a topic and without mentioing any names just let the gossips know how much harm gossips can cause and just how self centered it is to talk badly of others whether it is true or not to where they do not have to look in the mirror at them selfs.
