The sun was going down behind the hills when I reached a village which was only a few miles from the sea. The working day was over, and the villagers were coming home from the fields. Along the road two boys were driving cows and sheep in the direction of the village. I approached a group of people standing near the road and asked them if I could find a place in the village to spend the night. An old man said he would help me. He took me to his small cottage at the far end of the street. A fire was burning in the stove when we entered the house. One girl of about eighteen was preparing supper in the kitchen while two other girls still were doing something in the kitchen garden near the house. The old man invited me to have supper with them. They all seemed to be nice people and we were having a friendly talk. After supper my 'new friends and I went out into the garden. The moon was shining high in the sky, and the night was warm and beautiful. That evening was very pleasant, and I shall remember it a long time.
