Complication of mind

We've been running in the grass for several hours at this point, we didn't think of anything else. We were just running, my head wasn't able to comprehend it anymore, I couldn't understand why she was laughing, why she was smiling or having fun. I was staring at it, following her and trying to fake my own impressions to not feel cold. Even though that is already a hard task of its own. After a short while, we both laid under a tree. It was a beautiful maple tree. It was red, reflecting in the sun's rays more than it would normally. The sun itself was also falling under the horizon, creating a view of something very warm. Something nice and worth living for.
