The beginning of autumn. You don't really notice it. It sort of creeps up on you.
It's the beginning of a new season, a new fraction of the year.
But you're so busy with school starting, juggling friends, family, and sports, that you don't notice the first orange leaves, the first thin clouds floating lazily above your head.
But when autumn has officially arrived, it's hard to miss. The crisp, fresh air begins to carry a bit of a chill. Each morning holds a little more fog, and the crunch of leaves beneath your boots becomes sharper. The cheer of summer has faded, and been replaced by the concentrated seriousness of fall. The green in the trees has now been pushed aside by the reds, browns, and oranges that sprinkle the newly bared branches.
You start to spot a few round pumpkins sitting on a few porches nearby, and the spark of excitement that Halloween delivers every year flares in your stomach. But it's followed by a moment of doubt. Am I too old to dress up? To go house to house for candy?
But you push it aside with a sly smile. Age is but a number, my dear.
