How to stop people cutting me off when i am talking?

Haha, I've had coworkers who are jehovah's witnesses as well and not at all like that. I guess it depends -usually the most effective way to figure out whether or not they even realize that they are doing it is if you let them know that they are (in private of course- sometimes we just don't realize our bad habits unless someone lets us in on it). Usually it is a misunderstanding -if it turns out that is not the case you can go for the more aggressive approach of being a jerk and telling them -"excuse, let me finish... "/ "I'm still talking." while in the group -but I'm guessing if she is cutting you off in front of others they must notice it as well...
