I filled out the mailed census form and mailed it in on time. Around the first of June a woman came to the door wanting to do another form. I told her I'd mailed my form and sent her away. A few days later she was back, and I again told her I'd mailed my form, but she said this was a follow up questionnaire.
She then asked me the exact same 10 fucking questions that were on the mail form. The only difference was, I didn't have to sign this one. What a fucking waste of money.
