<p>I lock my door for two reasons. The least compelling reason is because we’ve had our car broken into in our driveway a couple of times and it’s only a few steps to the door. The most compelling reason is to make sure that our dog can’t get out and no one does the knock and walk in thing without our having the dog prepared because he would take a leg off and did actually bite our old newspaper lady when she walked in without knocking.</p>
