It rarely happens to me but now and again on here (and reddit!) something will just really keep my attention. Most recently it was about a woman's brother who wanted his gf to get rid of her dog. She was so short-sighted about the situation and a unanimous verdict that her brother was a cocklodging loser who had lived with the OP previously and the whole crux of the problem seemed to be that she didn't want him moving back in with her!
What was yours?
