the air in your lungs

Somehow she knew that you didn't get many moments like this in your life: moments when you knew, without any doubt, that you were alive, when you felt the air in your lungs and the wet grass beneath your feet and the cotton on your skin; moments when you were completely in the present, when neither the past nor the future mattered. She tried to slow her breathing, hoping somehow to make this moment last forever.
