Showing signs of being healed

Noah has realized that his "broken arm" doesn't hurt anymore when he raises it over his head and when he moves it around. This has led him to believe that he doesn't need to wear his sling anymore. If his sling is not pinned to his shirt, he'll take it off as soon as I'm not looking, as he did this morning. He hopefully only has a few more days to wear his sling. He goes back to the doctor on Friday to have an x-ray taken of his arm. It's tempting to just say he is healed and cancel the x-ray appointment since his last doctor's visit cost MORE than the ER visit, but I won't. It's still tempting, though.
