@t_locke Do you ever worry that advertising your location might encourage burglers?

People do ask me if I'm worried about telling everyone where I am, and I give a few responses:

1. There are two other people living in my house, which makes it harder to find a time when nobody's in.

2. I don't have anything worth stealing. Everything's worth a lot less these days due to cheap Chinese manufacturing.

3. The only time my house has been broken into, it was by the police.
