Make a Wish

I wish my head was a stone.
Thus, there was no space inside to think about these damn things.
I wish my blood was cold.
Thus, I would not have any feeling to get messed.
I wish my bone was made of steel.
Thus, I could carry anything on my shoulder and would not crash.
I wish my face was a mask.
Thus, nobody could see me through.
I wish I had a metallic heart.
Thus, I just need to change it as broken with painless.
Let me make a wish.......
