I am so sorry to hear of this terrible event. We send only our best wishes for her recovery, but know that it will not be quick or easy. She is going to need to fight to regain strength and mobility. You will be helping her to have the will to keep up the difficult fight.
This brings back memories of my oldest daughter in a terrible roll over car accident 12 years ago. When the State Patrol officer called to tell us of her accident, he cautioned that we should drive carefully to the hospital she was transported to. His concern was that in our concern and grief that we also might be involved in another accident. As you drive to the hospital many times in the next weeks and maybe longer, keep that advice in mind. You will be no good to Leslie if you get laid up. The roads will be getting icy and require the best of our driving skills.
The best to both of you!
