Well, this could sound political, but it is not. It seems to me that the USPS and the US Census are joined at the hip. Earlier this year I got a letter from the US Census saying that I would soon receive my official census form.

DUH! What possible good did that letter do except cost money? Then, one day a census taker drove up to my house and presented me with my official census. I told him I was expecting it in the mail because of the letter. He told me to read the letter closely and I would see that it said I would soon "receive" a census form, not that it would be "mailed" to me. Sure enough, he was right.
So, I filled out the census form and sent it back; tossed all the extra paper and the offer of employment. Last week I go to the mailbox and there is a postcard from the US Census. I figured it would be some kind of confirmation of receipt, but NO! It was telling me how returning the census was my obligation and blah, blah, blah. . . and oh by the way, if you have already returned your census form, thank you. Sheesh! How much more money are they gonna waste?
