You know after reading all that has been posted made me realize that there are a lot of just plain miserable people out there who have to find something to complain about cause they don't have a life and have to fulfill their lives by making other people's lives a living hell.
Mugsy, i know it's easier said than done, but try to ignore this sorry excuse for a human being. I find people like that, when they know they can rile you just keep it up. But if you let on that it is meaningless to you in what he does, gradually (Ihope anyways) that he will finally get bored with it and move on to something or someone else.
Good luck with the fence.
