Or is there?
I often go out with a group of friends - nice people - who have lots of fun talking in a group; not loud people - just talk a lot. I'm a bit quieter than most of them and find it hard sometimes to break into the conversation and say something as there never seems to be a gap so the only way I can say somthing is to talk over soneone which I think is rude of me.
But others seem to be able to get there two pennyworth in without talking over others.
