On Thursdays, I drop my daughter off at her chorus class and then find something to do with my son for the hour. We can’t stay and watch because he gets impatient and loud. Last Thursday, the last class of the year, it was hot–90+ degrees. I thought we might go to the nearby water park, but on the way we passed a construction site where a combo bucket loader and back hoe was filling a hole. The bucket was fascinating. After the operator pushed a pile together, the bucket came apart in two pieces and chomped down on the pile to pick it up. We spent the whole time watching this over and over again.
