Dale, try and remain calm. If it was anybody but your wife or son/daughter, go ahead and blow them off, or tell them off. Best thing to do is reason with your wife. You have to live with her. A good example is about 15 or 18 years ago, in a nightclub in New York City, a guy was trying to get even with his ex-girlfriend. Since he couldn't get a gun, he took 5 gallons of gas and started a fire at the nightclub he thought his girlfriend was at. Killed over 90 people. And, didn't get her, as she had already left the bar. Maybe if he had a gun instead, he wouldn't have killed anybody. Ya never know.
Try to explain that a gun is nothing more than a tool. Torpedoman is right. If you can, take her out shooting. Start with maybe a 22 rifle, and take your daughter along too. Good Luck! gypsyman
