Unloving HI

Actions undone. 
Feelings unshared.
Forever denied.

"Hi" is shortest (actually dangerous) word that can change your life..or affect you in the most surprising way you never thought you'd be. Can you imagine how many "hi's" are exchanged from two or more people each moment everyday? Some get along well together, most of them, maybe, are just passersby in one's existence. They don't need to care, do they? Anyway, the only thing i hate about "hi" is that it can turn into a "goodbye" in a blink of an eye that neither of you and the other person had anticipated.
