That Sound

The saddest sound in the world
Is the sound of you zipping up your suitcase
Knowing I'm not coming with you
That you can just pack up everything that matters to you
In a 21 by 9 inch suitcase
The two metal ridges being pushed
Sealing it all together
You have made the decision to leave
Leave me behind
Not be apart of my future
To not be present at my big accomplishments  
You had a choice
And you didn't choose me
And you left
I hate the sound of a suitcase zippier
