回复：今天在车上，我和女儿说起此事，我告诉她，

if you face a pistol, you should run away as fast as you can.
it is very difficult to hit a moving target 20 yards away with a pistol.
if it is a rifle, you should still run fast, although your chance of survival is much less.
lying on ground is not a good choice. you can cheat an animal. but you cannot cheat a human being.
