I'm guessing we all know a few people like that. I had a couple of customers who just about drove me crazy until I learned to let it go. If I said, "What great weather!" one man would say, "Nooooooo, it's too dry, we need the rain." If I said, "Nice to have a little rain," he'd say, "Nooooo, farmers have hay down." If I said I saw a robin, he'd say, "Nooooo, too early, you must have seen a bluejay." Or whatever.

I used to "argue" with them, prove my point. Now I say, let them be the fool. I've learned with those people you just have to let them win BEFORE you get to the edge. Unless it's a matter of life or death, I just say, "You're probably right", and change the subject.
