Why The Fuck?

My life is full of people entering in,
but eventually leaving..
It hurts so much more when they leave,
Do they even relise?
Whats the point of coming into someones life,
Being important to them..
And then Leaving?
With out a reason,
With out a care,
You just leave.
Is that even fair?
Like come on..
If I wanted you to just pack up and leave
Then why the fuck would I tried so hard?
WHY THE FUCK?
Is this what you planned?
Getting all close then being like forget it?
Why the fuck would you put someone though that?
