Broken bones

My oldest daughter was at her in laws house, that is on the lake and from what she said everything was going well, they were having a great time, but had to warn the kids to be really careful going up and down the deck steps while they were wet, since they were slippery. What did she do? Went up the steps, slid in water that was on the deck and tumbled down. She broke her arm from above the elbow to just under her arm pit. I feel so sorry for her since we’ve had pure record breaking heat, her arm is in a cast from under arm to wrist and of course she is in a great deal of pain. Besides, oldest child or not, she is still my “Baby”. She goes to the surgeon again in three days to see how it’s doing. So far it’s not healing normally and we are so worried she’ll have to have surgery, as he has suggested.
