Just to be clear, whilst it may seem 'unlikely' to some of you that I haven't had a form, received a visit from a civil servant, spotted the many adverts for the census, etc., this is indeed the case. I have not been living off grid in a mud hut in the Amazon, I do not shun email because I'm worred the CIA are tapping into my brain waves, I do not pull a camouflage blanket over my head every time someone knocks at the door... and I know how to open an envelope, have done so on several occasions.
