Either that or take em shooting to show there is nothing to be scared of.

The time before my GF went shooting with me. Another buddy and his GF came along. His girlfriend said she was terrified of guns, stayed very far away from the 50, and when she finally agreed to try shooting a gun; the 6" 22 revolver she was holding was probably moving 2-6 inches (at the muzzle) from her shaking out of fear when she held it up. Craziest thing I've ever seen.
