True story:
Took my wife out shooting.
Tried showing her (with all arms unloaded) the course in how to handle, don't point at anything you are not willing to destroy, not to barrel sweep anyone if there are people around.
She gave me the know it all bit about.. "Oh yeah I have shot guns before and I know how to use them"
O RLY?
Took her out and handed her the Norinco M98 (18"). put a 3" 2oz slug in her hand and said "Load up! Pull tight aganst your shoulder, take the safety off, aim and pull the trigger"
I she replied "I know what I am doing! shut up! Shotguns are weak."
BOOM!!! slug went downrange and she was on her butt.
"Whats that you say?"
"ASSHOLE!"
I tried to teach her to have respect for firearms and she thought they were toys that do no harm. Thats the whole reason why I did it. Next I handed her the 10/22, and she asked what this and that was and how does it work, I had no problems showing her since the shotty knocked that shit eating grin off of her face. Her whole thought processed changed and so did her attitude and how she handled them. Next up was the AR, AK, and the Taurus 9mm.
By the time we got home "she called two of her friends and was excited to tell them about her day out shooting with me and it was so fun blah blah girl chat"
Moral of the story is: I hate know it all's
