NO! Good luck to the girl depending on you for her safety - she's gonna need it.
She's gonna need it with the likes of you placing something that you point and click that goes bang in her hands when she gets in a situation she never should have been in using a tool she has no experience or training on how to use all under the stress of life threatening fear.
You don't get it; probably never will. Hopefully you and yours will never meet Mr. Darwin. Personally I wouldn't take that bet.
The guy has $400. Not $500. So he can spend $400. Get it? Not everyones rich. If i could buy a $200,000 bulletproof truck for my family, i would but just because they drive a regular car dont mean i dont love them enough to buy them better cars. I just cant afford it. Very simple.
