Last week my seven year old son had a really bad day at school. For the sake of his second grade dignity, I will not go into details. Later that afternoon, he went out into the middle of the yard and started digging a hole. I let him dig. I could see it was something he really needed to do. It's only grass. After about an hour he came in, feeling much better. Well, I looked and saw the hole was HUGE and DEEP! Dangerous. I let it go, knowing we had to get on with dinner and other evening rituals.
After a couple of days, when his psyche had returned to a more normal state, I said he needed to fill that whole back up. After about an hour, he came back in and said "problem solved."
I went out to the yard and the hole was carefully filled. Next to it was a new hole, identical in size and shape.
