I was thatching the lawn earlier this week, and I had the old grass in a big, neat pile on the driveway. The kids decided to dig in it. Then they decided to start throwing it around. And it got messy... real messy. There was grass all over the yard and the driveway and the sidewalk, and there was grass all over the kids (including in Vivienne's hair, which was a total pain to get out). I get major, major cool mommy points for letting them do this for over an hour.
