So quick question for you guys out there?

whenever i read love stories (cheesy ones, dont get me wrong) i find what the guy is thinking very interesting. there will be things like "her hair brushed up against my knee and i wanted to touch it so badly" and "i loved the way her nose crinkled when she was confused" and "i liked to watch her hair blow in the wind." i was just wondering if any of this is true? Do guys really observe every move a girl who he finds attractive makes? or is this just something you only read in books and see in movies?
