Have you noticed how two seasons can meet, then walk hand-in-hand a while?
How the leaves have gone golden, and frost visits the night; yet the days are still short-sleeved and bare footed?
How the gardens are (almost) cleared for winter, and the south-facing windows are swarmed with fall's flying insects (hello, box elder bugs!); yet the mower still mows, and the sprinkler still sprinkles.
How cold fingers wrap hot tea in the morning; yet by late afternoon, day's heat sends you outside to grill dinner, once again.
How it's wool weather and wading weather all at the same time?
This is the summer-fall stroll.
