So Royal Mail are now legally permitted to leave your post with a neighbour (hah! like that's stopped them in the past!) I have an eBay addiction so I don't want my many, many parcels left with my neighbours (who I don't know very well). So I've requested this opt-out sticker which Royal Mail say I need to stick on my letter box. When they see it, will my neighbours think I'm being rude? Are these stickers a sign of an unfriendly neighbourhood?
