Alethia - The Last Unicorn of a girl, or 101 Ways to look like a stalker

I've always had what I consider to be a healthy interest in girls. This has ranged from a purely 'continuation of the species' way (which has led to some awfully bad situations) to the sort of interest that one usually invests in wine or some other complex thing.
The idealized woman is beautiful in all the ways that man is not. I could expound on the Adam-Eve relationship or a 'Proverbs 31 woman' at this point but won't. A woman that realizes the effect she has on men is a dangerous thing but perhaps a fruit of feminism is that women tend to see themselves and aspire to be merely men with different plumbing. But a woman that realizes what she is and doesn't shy away from it (while also not using it as a means of influence) is a thing of utmost and indescribable beauty. She is marked by a manner of speaking that is not coarse, of dress that accentuates but is not scandalous, and a poise that endows her to be floating through this world.
It is a woman of this latter type that I've come across. Her name, she informed me in a precise, almost English way is 'Alethia'; a slim bespecled redhead that I met in the lift of my building. I chatted away with her like a chipmunk on speed as we waited for our respective floors and I learned quite a bit about her in that brief minutes' time. And in that time when the borders of my vision were all fuzzy as if in a stylized dream sequence, I neglected to ask her to coffee. Since then I have devoted significant deliberate thought in diving exactly how to 'casually' intercept her again. This has proven to be exceedingly difficult and frustrating considering that she lives but two floors above me. The fifth floor has become a sort of hallowed ground in my mind and I toy with the desperate option of simply knocking on each and every door on the floor to locate and proposition her. ( there are only ten apartments so I consider my odds rather good.)
Just where is that fine line that separates a well-intentioned, smitten fellow from a stalker? All this is probably for naught anyway; there are more dogs than Christians in this city but the improbable chances coming together would certainly go far in the divine hand thinking.
