With regard to the question of girls living in close proximity: there is experimental evidence to back this up; when a friend and I were playing around with coupled chaotic systems a while ago, my friend's supervisor gave us a reference to a few papers on this subject (thinking that maybe it was an example of coupled chaotic systems). I only read the abstracts, and I'm sorry I can't remember the references, but they indicated that this had been consistently shown experimentally.
