"If I take death into my life, acknowledge it, and face it squarely, I will free myself from the anxiety of death and the pettiness of life - and only then will I be free to become myself." ~ Martin Heidegger
I own and train for such scenarios. I only pray I wake up fast enough to implement my training.
I own a couple guns but have never felt the need to sleep with one . Lets try a different "what if" You hear a noise in the living room at 2:30 am. You jump up, grab your gun and go into the hall. You see a shadow moving close to the window, you take aim, pull the trigger and the intruder drops. You wait a couple of minutes to be sure no one else is there. Turn on a light and see your teenage son laying in a pool of blood. He was just sneaking back in after being outside. Do you still want to sleep with a gun?
I confess, I did it, I let the dogs out.
Before you criticize someone you should walk a mile in their shoes, that way when you do criticize them you'll be a mile away and you'll have their shoes.
