Buses, cars and taxis were not able to run and were standing by the side of the road. People were trying to find their way about on foot but were losing their way in the fog. Mr. Smith had a very important meeting at the House of Commons and had to get there but no one could take him. He tried to walk there but found he was quite lost. Suddenly he bumped into a stranger. The stranger asked if he could help him. Mr. Smith said he wanted to get to the Houses of Parliament. The stranger told him he would take him there. Mr. Smith thanked him and they started to walk there. The fog was getting thicker every minute but the stranger had no difficulty in finding the way. He went along one street, turned down another, crossed a square and at last after about half an hour's walk they arrived at the Houses of Parliament.

Many young ladies fell in love with him including the nymph : Echo. Nymphs were lively spirits who lived near streams and lakes and protected trees in the forest. Echo had upset the Queen of the Gods; Hera. As a punishment Hera made Echo unable to speak except to repeat the last three words of the person she was talking to. Poor Echo fell in love with Narcissus but could never tell him how she felt. Narcissus teased her and she ran away with tears pouring down her face. Aphrodite, the goddess of love saw what happened and decided to punish Narcissus. As he came to a pool of water Narcissus saw his reflection and fell in love with the vision he saw. It was of course his own reflection. Poor Narcissus watched his own reflection, every time he tried to touch the face of the vision he loved it broke up on the shimmering surface of the water. Narcissus stopped eating, lost his beautiful looks and desired to get his love. In the end he anguished gradually and died. Aphrodite took pity on him and made a flower grow in his place on the bank of the lake. Narcissus flowers can be found to this day growing wherever you can find water and trees.
