try it now.
and for better looks:

void talk(void)
{
	freeze(1);
	freeze(&current_sprite);
  if (&story != 1)
  {
   say_stop("I'm a tree.", &current_sprite);
  }
  if (&story == 1)
  {
   say_stop("`3Is it the well?", &current_sprite);
   wait(250);
   say_stop("Yes.", 1);
   wait(250);
   say_stop("I knew it.", &current_sprite);
   &story = 2;
  }
  unfreeze(1); 
  unfreeze(&current_sprite);
}

void hit(void)
{
say_stop("`3Don't hit me!", &current_sprite);
}
