The hardest goodbye

The hardest goodbye; you have to understand why
you have to let go; and what comes next you never know
a new oppurtunity you'll hope for; while one closes an old passage door
don't cry, it's going to be alright; i'm here with you, i'll hold you tight
it's hard to explain and hard to control your reactions; but when all of it passes by, all your emotions
you'll remember the day, you let it go; sensing you were right, it wasn't the end of the show
tell me you're right about what you did; many questions, few answers, please don't greed
the hardest goodbye; you have to understand why
first thing i did was cry; now i know it's for the better, it just another goodbye
