Tom and Dick are next door neighbor who both work in same office. They often walk together to and

from work. Once they were walking to home together while it suddenly started to rain. Tom quickly opened

his umbrella and said proud, "My wife really has great foresight. She said this morning it would rain and tell

me to carry my umbrella. "Dick smiled and walked up to her under the protection of the umbrella, said, "Mine

has even great foresight. She didn't let me carry one as she knew you'd share yours to me."
