Two vampire bats were hanging around in a barn on an isolated rural farm.
They were desperately hungry because the farmer had moved the last of his animals for slaughter, and there hadn’t been enough blood for them to feed on.
Finally, one of the bats said to the other: “It’s no use hanging around. I’ve got to go further afield to see if I can see some animals. I need to feed on some blood.”
The other one said: “But you haven’t eaten for days: you’ll be too weak to fly any distance.”
“I’ve got to give it a try,” the first one said, and he flew away.
Half an hour later, he came back. His face and his beak was smothered with blood.
“Wow!, said the second bat. Where did you find all that?”
“Well,” said the first bat, “do you see that village over there?”
“Yes, I can see it.”
“And can you see that church spire in the centre of the village?”
“Yes, I can see it.”
“Well I didn’t!”
