I imagine this has already been hashed out in another thread but here I go anyway....

At a birthday party for my boyfriend's young grandson, his ex showed up. She did not take kindly to my presence and behaved rather childishly. She was a complete idiot and basically tried to rather dramatically take center stage in an effort to come out as the alpha female present. Rather silly it was. Besides, the day wasn't about her it was about her grandson. How's about behaving with a little graciousness, eh? After all, my boyfriend and she split over 30 years ago. Get over it.
