Last week end, wifey and I were dining in a small neighborhood Greek restaurant. The place wasn't busy, so was easy to notice who came and went.
One guy... wearing flip-flops, t-shirt and shorts entered alone, stood in the doorway and looked around. Couldn't tell whether he was just looking for someone in particular or was casing the joint*. Nonetheless, I reached behind my back and grabbed my 9mm... just in case. Nothing came of it. He turned and left. But years ago, I never would have had such thoughts.
*Maybe I'm just being paranoid these days, but a few years back a couple of punks robbed a local pizza restaurant and killed everybody inside. I guess they didn't want to leave any witnesses.
