About 2 years ago I held an intruder at gun point when staying overnight at a relatives. Told him to get on the ground and not to move, and if he did move he'd end up with a bullet in his chest.
Called the cops, they came and apprehended the guy. However when I first saw him I did almost pull the trigger immediately.
And then there was a year ago I got in a nasty fist fight with my sisters ex-husband. The wife and I were visiting my parents and my sister had come over with my nieces. The ex started stirring some stuff with her and things got bad. He started yelling and hit her. I stood up and tackled him onto the floor, punched him in the face and broke his nose. Stood up and kicked him a few times. Ended up breaking a few of his ribs.
What a great family visit that was.
