Well changing a woman's mind is sometimes....well just impossible.
I am a lucky one as the wife loves guns, my daughter started off hating when I carried. Always asking if I was expecting trouble or looking for it, rolling her eyes at me. So I kept her in the dark for a couple of years, till she turned 13 and took her shooting at the local range. She had a blast with a .22LR rifle.
One day she got scared when a drunk pulled a baseball bat on me over at a cook out at her friends house. Later that night she asked if I had my gun with me, I told her I did, she asked why I didn't pull it out on him. I told her that the need was not there because he could hardly stand up let alone swing the bat without falling down. Then the light came on as she saw I wasn't looking for anything by carrying, I was just being prepared. Now I'm happy to say that she carries too.
Don't question my right to own a gun and I won't question your stupidity not to.
You give Peace a chance, we will cover you if it doesn't work out.
