This past weekend we had our first really hot weather. The temperature got up into the 80s, and suddenly it was like summer outside. I did some yardwork, and as I was pulling the weeds out of the cracks in our brick sidewalk I heard the first sounds of the summer season — the throaty humming of lawnmowers, the shouts of children playing hide-and-seek, the beat of a basketball on a driveway court, the whirr of bicycles rushing past, and the distant calls of parents for their kids to come in for dinner. All of these sounds come from people who are outside, doing outside things, after the long winter has ended. These summer sounds are welcome, and are as much a sign of the changing seasons as the rising mercury.
