I imagine various scenarios and how what would be the best course of action. I think that's more "precautionary" than paranoid or crazy. I like to try and think like a criminal and imagine what they would do to gain entry. When I get back in the farmhouse am definately going to replace some doors, although if someone wants in there are plenty of windows they can smash and walk on in.
Like Jocko, I do the same things on my bike when I ride. I take it a step farther and just pretend I'm invisible and no one can see me, so I expect cars to pull out in front of me or change lanes on me (although with my pipes I don't know how they can't hear me). I had one guy, I could swear we made eye contact, but he pulled on out and I had to hit the brake hard, fortunately I was already off the gas and ready to hit the brakes hard. He got the one finger salute for sure, although I'm sure he couldn't see it.
