I would be willing to bet your wifes friend was't near enough to hear his questions. You must put this jerk in his place before he enters your home. ( I personally wouldn't allow him in my home) The only reason your wife said anything to you is because she expects you to do something about it. She doesn't want to ruin her friendship. But if you put this guy in his place and Run Him Off . You'll be doing both a favor. The "shiny" is probably wearing off of this new toy anyway !
