Honestly, no one in their right mind would break into our house. There's two reasons for this. One is that our three dogs bark like crazy at anyone walking by the house on the public sidewalk. If someone comes into the yard or to the door they go nuts. They sound like a wolf pack. The second reason is that we have nothing material worth more than a human life. Let them take what they want. It's all insured.
Come to think of it, there is one more reason. The West Linn police have so little to do, they'd be here before much could happen. One time they followed me into my driveway simply to let me know one of my taillights was out. You never see a panhandler or a vagrant in this town. The police are on them within minutes of their arrival.
You missed the broader point. As chaos said, you live in a very safe Lilly White neighborhood and feel safe. Good for you. You play the odds and don't feel you need to protect yourself or your family. Some, actually many, aren't so lucky. You don't have to have bars of gold and piles of diamonds to get your house broken into and robbed. Poor neighborhoods have a much higher level of crimes of all types.
So take a big yawn, pat yourself on the back, boast about how you never have had to defend yourself, others, and your property. Just keep in mind things can go south very quickly. You're old so most of your life is behind you. Some are in very different circumstances and choose not to be so complacent.
