Autists tend to like systems, I guess because they’re complex but logical and predictable. Road signs and maps fall into that.But MILITARY, dude. Sexy, sexy MILITARY. Uniforms and guns and maps and sides to take and people to dress up in sexy sexy military gear and be admired! Fuck, you just don't get it, do you?
In a way it's kind of interesting to see how Phil has his psychosexual wires crossed so much. His map obsession is linked to his weird peepee tickles when he sees people in uniforms who have power. Not quite sure where road signs fit in. Up his voluminous unwiped ass, probably.
