After a dinner party at a friends house I said on saying goodbye to someone I had just met that night, "I hope we do not meet again".
I really did not realise I had said it, ok I did not particularily like the man but would never have imagined I would come out with such a remark.
He went on to become a partner for a while of a dear friend, I was never invited to functions when he was present, I wonder why?
