Well that is a new twist on my story -girlfriends babbling away when their guy is on the phone to a bud?
I think that I said to my lady friend( ex)that her behaviour was rude, intrusive, disrespectful and socially primitive. Those words equally apply to some female who cannot be quiet long enough to let a guy talk to his friends on the phone. If I had a pet parrot and it squarked away in the background when I was on the phone, I would open the cage and grab it and point it towards the nearest big tree.
This interfering behaviour is a boundary problem too.
It seems that these women do not understand where and when your busines is NOT their business. Open those cages guys !!
