It was so cold. We did not see any butterfly.

Only a broken wing of the them was found on the floor.

We met a woodman on the way. Why we can not see any butterfly today, the teacher asked him.

The woodman told us they all hide in the deep valley.

We still can not find any of them after walking so far away into the valley. We went back to school without anything at 09:00am. We were too disappointed to take any picture.

The woodman said that all the butterflies hide in the deep valley. Is it a clue?
