When my son was in nursery school I would pick him up after work and use the drive time to teach him things he should know. One day I realized that some children in my class (third grade at that time, I think) did not know their addresses, and I wanted to know if my son knew his. I asked him what street he lived on and what was the number of our house. He answered correctly. Town? Also correct. State? Correct again. Country? He didn't know. I told him, "United States of America." He said, "Oh, United States of America and to the republic for which it stands, one nation under God with liberty and justice for all." (For those of you outside the US, that's how the Pledge of Allegiance to our flag ends.)
