I've been carrying so long, live in a very gun friendly state, and have so many family that carry, that I don't even think about it anymore. But I do remember the first time I went armed. It takes a year or so to get over the constant knowledge that you're carrying and I've talked about it with my family members who came of age and decided to carry.
Last night I was at a family gathering, and I'm sure that four of us were carrying. I never bothered to look. It is what it is. But, with getting comfortable while carrying comes the full knowledge that the vast majority of the people we see don't give a flying damn about anyone but themselves. They're either obsessing over the cell phone, working a list for shopping, or being virtually oblivious to everything around them, including me. I don't talk about carrying much, because everyone that knows me knows I'm carrying.
