Stanley and Frank are next door neighbor who study in the same class, so they walked together to and from school. Some day as they were walking home together, it sudden started to rain. Stanley quickly opened his umbrella and said, “My mother surely have foresight. She said on this morning it would rain and told me to carry my umbrella with me.” Frank smiled and walked to him, said, “My mother has even great foresight. She told me not to carry an umbrella and as she knew you would certainly have with you. Don’t you agree?”
