Why can't these memories just fade away..?

I wrote this about two months ago while I was sitting by the window during a free hour in the class when everyone were in their highest spirits and me, in my lowest..

Voices and whispers,

the wind cunningly brings to me

torments my mind

as it echoes the sweet words uttered,

the many promises made

words and promises that remained

just words and promises

now tinted with bitterness.

A mocking laughter

that echoes my own

rewinds my mind, when I laugh

and regret at the same time

for it brings back to me the funniest times I've ever had

funniest times that made my life painfully more funnier.

Just a glance

and my mind rewinds further

and stops just when I smile

and frown at the same time

for it stops at the memory, I most cherished

and the one I most hate now.

Voices muffled with laughter

and those sideway glances

just adds up to the aching memories

memories that I wish

would just fade away...
