I'd let you die on your death bed...

I blame you..
For the reason why I'm alive,
the reason why you left,
why I am hated by most,
before they get to know me.
I blame you for breaking her heart,
and leaving it up to her children to pick up the pieces.
She works hard to support us,
I admire that about her,
and I still blame you.
After having said that,
I know people tell you not to blame other people,
for the mistakes in your life.
But when you think about it,
I didn't make the biggest mistake,
You did.
Let's just say...
If you need a kidney,
and I'm the only one who can give that to you,
I'd laugh and let you die on your death bed.
