Not sure I would have noticed if he'd been flexing a concealed weapon, unless he'd been very obvious about it. It's just not usually something I'd think about. "Hey, is that bulge a concealed weapon? Or is he just really happy to see me?" With that guy though, I think I would have felt the threat of physical violence whether he'd had a gun or not. It was in his body language, his expressions, the tone of his voice. What the gun did was make his threat more real, more up close and personal... and, ultimately, more deadly.
The whole situation reminded me of kids on the playground who bullied me as a child. Even one event in particular in which they stood in a circle and pushed me around, until someone finally had the decency to punch me in the face and take me down for a while - ruining their fun. The difference here was that this was a single bully who was far more dangerous, as well as being armed with a weapon that, within a second or two, could have splattered my brains all over the hotel desk.
I'd love to write for a living, but I have some issues with my writing. Grammar, sentence structure - even descriptive writing are, to some extent, difficulties of mine. The genre I enjoy the most (fantasy and sci-fi) tends to require rather elaborate descriptive writing. I can describe a human being pretty well - but their clothing? The hill they're standing on? Maybe not so much. I think my ability needs a lot of polishing - but it is my goal to write for a living some day.
I don't think I'd ever want to own a gun myself. Maybe if it was the end of the world and we were living in a zombie apocalypse or something... but, generally, guns scare me. The simple knowledge that all someone has to do is point and pull the trigger - and bam, lights out.
