a promise made... a promise broken

I promised you something,
One night when you were weak,
That I would always be there,
When my help you did seek.

I meant it,
To my promise I remained true,
I was always there,
No matter what I had to do.

One night however,
That promise was broken,
You cryed for my help,
But no words were spoken.

You tried to wake me,
But it was only in vain,
I was deep in sleep,
I couldn't numb your pain.

I am so sorry,
I hope you forgive me,
It wasn't on pupose,
I didn't mean it you see...
