Whenever I am in a big audience, like lately at my daughter's dance recital, I feel like I am a weirdo because I am always looking around for escape routes, likely attack points, possible shelter, possible ambush points, counter-ambush points, flank routes, etc. I'm always also casing the weirdos out in the audience, seeing if they have bags / back packs, seeing if they set them down and leave, see if they look like they're heavy, etc. I watch their shirts for belt-line bulges as they move around and bend over. I look for bags without owners, hawk-eye them for minutes at a time until someone finally picks them up. I'm not military-trained or anything, its just something I naturally think about. I would say that, even at her recital, I gave about 50% of my total attention to her and the other 50% toward tactical planning. Is that weird?
