~~~~~~~~~~Oliver's P.O.V.~~~~~~~

My little toddler legs run as fast as they can through the soft green grass, in the little meadow, sunlit and covered with the lightest layer of dew. I chasing (y/n) my best friend. Neither of us were the fastest, but she still outran by just enough where I couldn't grab the back of (f/c when you were little) dress. This meadow was our little secret. Not even our parents knew about it. Soon I was able to grab onto a handful of fabric and she fell to the ground, and I along with her. Soon I was very worried, due to the fact that she was holding her knee and sobbing.
"What's wrong?" I asked, really worried for my best friend.
"Oh nothing, just scraped my knee when I tripped." She said.
"Want me to kiss it and make it all better?" I asked simply, knowing this was what our parents did when we got hurt.
"Okay." usually this would be weird, but Oliver was a close enough friend where it didn't feel weird.I kissed (y/n's) knee and she grinned.
"Thanks." she said. "It's all better." We then both laid down in the slightly damp grass, staring at the clouds slowly moving over the blue sky.
"Hey Oliver," (y/n) said suddenly after about 10 minutes of cloud-gazing.
"Yes (y/n)?" I asked curiously.
"We'll be friends forever, no matter what happens?" She asked, looking over at me with her (e/c) eyes staring into mine.
"Of course (y/n)! We'll always be friends, no matter what."
"Promise?"
"Promise."
We made a promise unbreakable for any child, a pinky promise. (y/n) then slipped her hand into mine, and we looked up at the sky, now dotted with the brightest stars as the sun began to plummet behind the horizon.
