Be there...or not?

I open the door,
And saw nothing,
Just a speckle of dust,
It irritate me,
And makes me sad....

Thinking back,
I always open my door,
For anyone to come in,
To share their happiness,
Their sadness, their anger...

When somebody need me,
I was there for them,
When i need somebody,
I doubt that...
There'll be somebody for me."

So what do I do now?
Being nice for nothing?
Being good for the worst?
Or...should I changed?
Into the worst? Better?
Or remain invincible?

I guess,
Just being there,
Is not really enough,
I think,
That I need attention too....
Should I be there for someone?
When I doubt that there'll be someone,
Who will be there for them?
