D
One day John took two of his friends into the mountains. They put up their tents and then rode off to the forest to watch how the trees were growing.
By afternoon when they were about ten kilometers from their camp, it started to snow. A moment later, more and more snow fell. Soon they could hardly see the road. John knew there were two roads. One road went to the camp, and the other went to John's house. But all was white now. Everything was the same. How could he take his friends back to the camp?
John had an idea. The horses! Let the horses take them back! But what would happen if the horses took them to the wrong way? That would be a long trip in such cold weather!
It was getting late. They rode on and on. At last the horses stopped. Where were they? None of them could tell. John looked around. What was that under the trees? It was one of their tents!
