"Watch out!" She screamed frantically, her face in horror as the world blurred past me. "What were you thinking?!" She dashed out straight in front of me with all of the speed she could spur in her small, sleep deprived body. Two words, "I'm sorry." Were all she could manage to muster in a gulped and strangled whisper when she looked me in the eyes for the last time. It was so quick, and I still remember how tear-filled and sullen her eyes were, but they showed no regret. Maybe that was just my mind trying to comfort me, but I'm so sure I felt it. She forcefully slammed me towards the grass, tears streaming down her rosy cheeks as the truck only ever sped forwards. She had spoken to me from her heart. I fell to the ground, hard, and didn't even bother trying to get up. My life was over. I burst into sobs of the deepest sorrow I'd ever felt. It dug into my chest, it ate away at my soul, and I felt so goddamn useless. The way I had yelled at her before, the arguments we'd had, I realized how foolish and petty they were, and despite everything, she still gave me my life back without second thought. I was petty. So petty and so lifeless.
Only after seeing her torn up, mangled, and barely recognizable body did I realize what dead really was. Life hadn't ended for me, it'd only just begun, and it will only ever move forward. I only then recognized all of the opportunity there is because life is only temporary. That's what she had been trying to tell me in her old, stubborn fashion. She sacrificed herself to tell me there is always an opportunity in life, my ignorance and pessimism just never allowed me to see it until it was too late.
Way too short for my liking. Maybe add some more paragraphs or sentences overall, that's a problem with a lot of blogs the past few days.
Just some advice.
