Dying for My Adopted Brother's Sake

I struggle with all my might, but Dad restrains me, and Mom breaks my limbs. Then, my sister seals me into the concrete.

"Concrete is only brought to life with an actual person sealed inside. It looks so much more defined! It's not like you'll die after being sealed in there for a few days. How can you be so insensible?"

The pain of having my limbs broken and my oxygen being cut off leads to me dying within that block of concrete. My body rots and festers inside, but my soul sticks around to watch how my parents dote on their adoptive child. They seem to be happy without me.
