kinetic \ki-NET-ik\, adjective: of or having to do with motion; caused by motion

Moving forward, I think about the feet inside my shoes. And I concentrate on the heat on my arms and the slight breeze at my back and the evenly spaced trees that line the street to my right. I keep my eyes on the sun-dappled sidewalk and my steps inside the connecting shadows of the elms. One foot in front of the other.
When I feel like skipping, I do. Knee up, heel back, toe push up. Knee up, heel back, toe push. Arms swing. I make my hands into fists. I try to skip higher, and higher. Each step more fierce than the one before, briskly flinging myself forward. Stop. Walk again. Fists still swinging. It's a fast walk, until I'm running. The trees whisk outside my peripheral vision. I watch the lines and cracks of the sidewalk slip underneath me. The air that was warm is now chill on my face and arms. I feel goosebumps raising. And I push my legs and the bend of my knees to work harder, make me faster. I do my best to breath in through my mouth and out through my nose. Only when I feel the cramp begin under my ribs, and see the numbers of my mailbox, do I slow down.
I turn left, go through the gate of my house, walk up to the steps and enter beside the stairs to the second floor, make my way to the kitchen, pour and drink a glass of milk from the fridge, set it in the sink and leave the house again through the sliding glass doors behind the kitchen table. I walk to the edge and lay down, stretching out my body to its fullest length. After a deep breath, I throw myself over. I laugh into the green grass as I roll down the hill, stealing glances of the blue sky as I flip, flip, flop to the bottom.
