So where do I start?

I've bullied you for so long.
Told you you're fat,
then anorexic,
then ugly,
then silly...
The list keeps going on.

Recently I saw the scars on your wrist.
I really never saw them coming.

I didn't think you'd do that.

All the things I said I never meant. That's how we used to play.
I never thought it would have this kind of impact on you.

So please forgive me for all the things I've said.
If I ever hurt you, which I now know I did, please find it in your heart to forgive a blind fool.
He who never saw the damage behind a hurtful game, now regrets all the love he wasted on others.
I wish this is just a phase that ends up soon.

I've bullied you for so long, but isn't that what siblings do?
