Apparently we have it! Since summer vacation started, not just one, but TWO neighbor kids have broken arms at our house.
The first was several weeks ago. We moved a bunch of rocks from our neighbors side yard to a pile in front of our yard in preparation for getting cement. A neighbor boy was riding his bike over them and fell. Snap, one nice straight arm down the drain.
The second was yesterday. Dawn and a friend were playing outside. I heard screaming and kids running in. In came the friend with a very obviously recently-bent-where-Heaven-never-meant arm. We took her home, brought back two of her brothers and she returned a few hours later with a nice pre-cast splint.
Oh dear, what have I done to deserve this? And even more frightening, who is next?
