Do you know this guy?

I have the displeasure of being exposed, several times per week, to a man with absolutely no social graces. There have been jokes made about people with no social skills saying things like " Nice weather huh?" I would like to share with you some of the nerve grinding things this person says. First, the " are you depressed today?" This is said each and every time my football team loses. As if, one day, I will bite and say " No.... why would you say that?" It reminds me of the ' you've got something on your shirt gag ' waiting until you finally are caught off guard and look down to a pop in the nose. Ridiculous. Today - I got " I think about half the leaves are off the trees."..... just randomly, without provocation. Reader, can you let that sink in - picture it even? Is there a proper response to that? I just nodded in disbelief. Are there people who just hate silence? Those who kill the peace and quiet at all costs - even if it makes them appear to be complete idiots? Meanwhile, I have tasks that need my attention and my complete brainpower focused on them. Oddly, this man is not without his abilities, nor would I describe him as ignorant. I have decided... I blame the wife. I have known women who have this sweet " all is well" attitude toward their husbands and never encourage them to be all they can be. Don't get me wrong, there is something to be said for being accepting of other's shortcomings- after all, no one is perfect and I realize that. But never addressing these random, inappropriate thoughts, have bred a full-grown man who acts like a child with no edit button. He has alienated virtually everyone they come in contact with at one time or another. Whether it be fear of conflict, money-motivated, or just too big of a job - I can't pinpoint her avoidance. She is an intelligent and strong woman. I consider her a close friend. When I watch her interact with him I hear " That's good hon", " Wow, that's neat" and other child-like encouragement for this behavior. I refuse to encourage him. It's my first reaction to give the Jim Carey face and say " very good " in my most condescending and sarcastic tone. Is she just far more patient and kind than I? Would their marriage fail if she simply said " why are you saying that", or " you are making yourself look very stupid and I know you aren't" or any other phrase that at least addresses that she recognizes his inability to edit. I think that overall our partners balance us. They are better at saying potentially insulting things because there is love and a lifetime of experience to balance the blow. So I am inclined to say it is a spouse's / partner's job to bring to light failings and /or issues that are so frustrating to so many. My husband, on the other hand, would probably love more " that's good hons" from me. I just can't seem to help myself, but to confront him - usually in private - when he has made a complete fool of himself or has hurt or bothered someone. Isn't part of loving - teaching? The truth, spoken in love, is very valuable and necessary.
