Did I do the right thing by telling my wife to just close the door and get the gun? What would you have done?
You did good... your wife on the other hand is a bit too trusting and blasé. There's a Clint Smith quote I like... "When seconds count, the cops are just minutes away."
Another is "Be polite, be professional, but have a plan to kill everybody you meet". I don't know who to atribute this one to, but it's one I tend to live by.
