( Bob groans . ) What's the matter.Bob ?   I think it's my ankle .   What happened ?   One of my snowshoes got caught on a rock .   Can you stand ?   I don't think so.It ' s kind of sore .   We'll have to get you to a hospital for an X-ray .   Is that really necessary ?   It may be worse than it seems . How's it feel ?   About the same .
