You realize that your situation is dire, and that no matter who may be out there, you need help. So, you take the chance, hoping that the person out there doesn't want to do you harm.
"I'm over here," you yell as loud as you can. Then, you regret it because of the following pain.
It takes you a moment or two to gain your composure. When you think you can finally yell again, you shout out for more help. You hear some rustling in the nearby trees. Your heart begins to race. Finally, a man steps out of the woods.
"There you are," he says, coming up closer to you. "What seems to be the problem?"
"I think I have broken my arm and leg."
He looks at your left side. Is it that obvious? you think.
"We need to get you some medical help. I'll call the park ranger and get you to a hospital." You begin to protest, but he won't hear any of it. "I may be a stranger, but you need my help."
