I didn't, but then I got ptsd and now I do, and have for a long time. Nothing ever happens and I don't want it to, but there's an instantaneous thought that occurs. It's not like a macho comparison, though. It's like a survival mathematical thing. It's more like, "what would I need to do if that guy pulled a weapon, or threw a punch or something? Would I need to grab something? What's within view?"

It's over in a second and I barely notice it now, but it used to keep me off of public transportation or other crowded places because it was too much to keep track of and I had trouble keeping up my end of the conversation. Frankly, it's really fucking tiring.
