You know my grandfather now past was a great man, but he divided opinion amongst those who knew him right to the grave, one of his favourite sayings was:-
I am not always right, but I am never wrong
I always took it for good humour but there are some people who practice that view, and I was one of them when I was a teenager, were never as mature as we think we are, you girls need to step back and consider how this pointless bickering reads to everyone else, it's not what they expect to find when they come here, and not something they'll come back for, it ruins it for everyone.
