Sneaky peek or Heart wide open?

I always giggle when i see a guy having a sneaky peek at a pretty girl or vise versa. Either on the street/bus/tube/ferry, we've all done it and it's pretty enjoyable. Question is, when did we have to stop showing others that we find them interesting?

Or maybe a better question would be:
What came first the interest or the rejection?

We've all been rejected in some way and unfortunately alot of us do not take what we can from it and instead harden and become cold (good or bad that's up to you). It's a damn shame the she never wanted him or that he cheated on her but in all we live and learn or do not live at all.

But then there comes expressing to those you know, love and trust. Some can, some cant. I've been told many times that i'm 'distant' but then i've also expressed my feeling to those close to me and recieved uncomfortable reactions, leading me to believe the reason we were so close is that i may be quite distant and that they simply enjoy and find comfort in not having to 'deal with all that stuff'.

Those who demand attension and reassurance that you care... well i've never got on with those people. Forced is fake and silence does NOT mean you dont care.
The very fact in can sit on the sofa next to someone without the need to speak should tell them something and to be honest i do not really feel the need to entertain their insecurity if they cannot see that.... Thoughts anyone?
