when ur used to, its hard to let go..

I must admit now.. its hard for me to let go. I just found out that one of my friend here at work was resigning.. it hit me and at the end, makes me really sad... in the past, i thought it was just a denial,  but now, i realized, its more than that. Im such a coward, that cant accept the very reality that people come, and people go out of our lives. its hard to digest that most of the times, we are getting used to have our cherish ones near us, but we cannot used to in lossing them... Thats why, I cant handle goodbyes. I cant bear to do so, to a point that I would be the first one to go away rather than the one left behind. ITS SO SAD. I just wish I can take a gasp on those people, BUT, ITS WAY IMPOSSIBLE. I want to savour the moments.but savouring it would prolong the verdict. I JUST WISH THINGS ARENT CHANGING... HOW I WISH..
