Everyone had a smile on the face. The teacher went to the blackboard and wrote "SMILES" on it. "This is one of the lwords in English", he said to the class. The whole class laughed, and then one girl sup and said, "Why is it one of the longest words in English?" The teacher said nfor a while. Then he smiled and said, "B there is a mile between the first letter and the last."
