Did your elderly mother-in-law that lives with you mention that some nice person came around and she gave them your information? Is your neighbor that you never talk to the only one who is always in the neighborhood? They reported your information for you. Enumerators usually do the best that they can, but too many people slam the door in your face saying "I'm not telling the government anything" and too many neighbors have no idea how many children you have, let alone their names and ages. So in 2010, Americans, give that enumerator a break, be as helpful as you can or refer them to the other neighbor who knows more about the missing family than you do. Your descendants will thank you for it.
