People are just.... Awkward.

I had an experience the other day, and the more I think about it, the more I realize it happens a lot more than I know.
Have you ever walked, well never mind of course you have. So lets say you were walking, just down the street. Or on campus, whichever you prefer. Someone is walking towards you, and in my case lets say he is a man/guy/boy..... you get the point. He looks pretty cute, but you can't tell because he's still a little further away. As you near each other, you feel as though you have been staring him down, which you have. Then the thought comes into your mind, "Oh dear, he knows I've been checking him out!" Now your scenario doesn't have to match this exactly, I just want to explain my point of view, and what usually happens to me.
Now he can feel you've been looking at him, and soon the most awkward part of this story comes into play. -Should you make eye contact? -If so, how early? -If you make eye contact early enough, you could be staring at each other a lot longer than needed, and thus resulting in an awkward stare. -Or if you try to look too early also, and he doesn't look, then the awkward feeling settles in no matter what and you feel like a retard. -If you make eye contact too late, you could definitely miss your opportunity of any contact at all and just stare at him as he passes by. -If you decide not to make eye contact whatsoever, you come come off as rude, ya know? -You don't know if he's ever going to look or not! -But what if you don't want to make eye contact anyways? All that staring and attempting to find out a lot about this person has completely gone down the drain. Oh the complicated thoughts of a girls mind.....................
There are many more "scenarios" in which this awkward passing-by can occur, but either way I figured you're doomed. You never know how early or late to look at the other person, ever. I bet you have a 1 in 50 chances of an awkward passing NOT happening, just a wild guess. So, good luck to ya!
