The graveyard was dark. It was... Scary. I was just visiting my dad's grave and I heard something. It sounded like a growl. A low, growl. It came closer. It was there. Right in front of me. Breathing heavily. I blinked and it was gone. What was it? I was blinded by confusion that I forgot about my dad. I left, without even leaving the flowers for him. I felt regret. Forever. It kept clinging to me. What was it? I should've kept that question in my head instead of searching for the answer years later.
