We have a group of friends who get together once a month, most of us worked at the same place years ago, though no one is still there. Recently one of the ladies got divorced, and is living with another friend, whom none of us knew. She has started coming, which is fine. But she is such an "expert" on everything. If you say anything, she has to either prove you wrong, or tell you a better way to do something. Getting on my last nerve!
