 ''Oh, it was great, Dad.'' ''Did you see how poor people live?'' the father asked. ''Oh, yes,'' said the son. ''So tell me, what did you learn from the trip?'' asked the father. The son answered, ''I saw that we have one dog, and they had four. We have a pool that reaches out to the middle of our garden. They have a creek that has no end. We have imported lanterns in our garden. They have the stars at night. Our patio reaches to the front yard, and they have the whole horizon.''
