Unfortunately my wife has been dead for 4 years now. That's a conversation stopper. I'm sorry to hear that. When the conversation starts going in that direction it isn't easy for me to find much humor in the reference regardless of the intent. In better days when she was still healthy. http://homepage.mac.com/lco/filechute/Sue-2Aw.jpg -- Regards, Savageduck |
