There’s dog poo all over the yard!

Leaving work yesterday, I noticed the groundskeepers aerated some of the lawns on campus. You know, when they take this machine that yanks little plugs of dirt out of the ground and leaves little holes so that air can get into the soil. Supposed to be good for the lawn or something.
Anyway, it reminded me of the times the yard of my elementary school got aerated. Of course back then, I had no idea what it was all about. I’d just walk to school one morning, and see all these holes in the ground along with what looked to be dog poo scattered all over. I never got any closer than the edge of the side walk, because I didn’t want to step in a field covered in poop. That’s just gross, you know. So I would crouch down at the edge of the field and visually inspect the poo (trying to figure out just what the heck it was), and look down the little holes to see if I could spot whatever creature made them. It didn’t smell like dog poo though, and eventually I figured out they were just little plugs of dirt mysteriously dug up sometime after we had left school.
Even now, to this very day, I always stay off freshly aerated lawns, because you never can tell when one piece is just a lump of dirt, or if it really is dog poo.
