Grey Areas

As inspired by Sam previous post, I have decided to ponder on this. I HATE grey areas, and by that I am referring to the one in relationship. How do we define grey areas then? As in, where do we draw a line between that shade of black and shade of white?
Can some1 please tell me, what's the difference between good friend and 'the one'?
It seems to me that there are so many similarities:- you alll can have heartfelt talks, you all enjoy each other's company, hmm...so does the difference lies in, whether u2 wish to see and be with each other at some time?
Guys out there,plz oh plz, DUN send the wrong signals and make our lives miserable. My dearest fren just got out of a major suckfest, thanks to some guy who doesn't practice avoidance though he has a gf alr. I dislike guys who flirt though they have gfs. And recently, another fren (not so close) of mine had prob with his relationship because he was caught red-handed in a club,holding ANOTHER gal's waist, and the gal was sitting on his lap. He may have been drunk and it was 'unintentional', but mistakes done, heart broken, what more can be done? The best thing I can think of is, let TIME heals. If he still cares for her, he will show her that he still cares(though the amount of effort from his part must be pumped in, and there is no guaranteed success), and let her be the one to decide, whether she can forgive and forget.
According to some of my guy frens, a normal courtship process is as such:
MSN, sms, phone call, outing (just u2 as fren), then more outing, then THE QUESTION asked.
Is it so?? haha... and tell me, who long must u all venture in each stage? it seems that some people take 4ever to reach the final stage; trust us guys, we don't have forever to wait for u all. 'According to the practice of elegant female' (borrowed from Pride and Prejudice), we don't go around telling guys 'i like you'. We are waiting for cues from u all, ok? haha...
