You're dead right Bob. He's one of those people who could have an argument in a room on their own*. No matter what you say, he counters it, more often than not by just repeating himself, then stating that it's his opinion and he's entitled to it - at the same time totally ignoring the fact that others have an opinion to which they, too, are entitled. I ignored him for ages, then made the mistake of engaging with him the other evening. Never again - he is so ****ing boring.
I guess we should feel sorry for him - I get the impression that he's just a poor, lonely soul, without much of a life.
* = reminds me so much of my first wife that it's frightening.
