Well I am really sorry to hear that you had to live through that. But also I want to congratulate you that your wife is going to go the mile for the permit.
I am lucky that I have never had anything like that happen me or been in any situation that would cause me to use a firearm.
However, I am proud and glad to know that I am able to use a firearm (and I must add I can use it well...hehe ) in case I ever have to come across the event I may need it.
Once your wife does get it, she will start to think..."How did I ever live without having the security I have now?" At least that is how I feel.
So once again, Congrats and my condolences.
