Longtime lurker here- (joined to get bf advice but never managed to post, too busy bfing). I promise I'm not a bin troll.
NDNs have an unorthodox way of putting bins out. They get taken very early here, so most put them out the night before. Not NDNs. They have a lie-in, then nip out onto pavement at noon and swap their full bin with an empty one while we're all at work, ignoring big number stickers etc. (I've always wondered what they're up to, but now I'm on mat leave I've caught them at it!)
DH (irritatingly zen) says life is too short to care who has which bin, but I think it's cheeky- someone who put their bin out ends up with a full one for two weeks! Are NDN BU? Or am I being (as DH puts it) a Bin Loon?
