Through My Mistakes (I Became One)

"It wasn’t until I lost everything, that I appreciated everything. From the sky to the sea. From the black Impala and their long hair and green eyes. It wasn’t until I realized I missed seeing the demons and I missed seeing black eyes and sharp teeth, twisted men and monsters, that I was truly lost. But most of all, I miss His blue eyes"
