It says which one is correct? Neighbour's or neighbours'. Yet they never state whether one person lives in the -blam!-ing house, or more than one! Therefore either one of those can be correct! How am I supposed to know whether they mean one neighbour or more than one neighbour!? This is mother -blam!-ing bullshit! You don't need this -blam!-! As long as you know what I'm on about it doesn't matter what the -blam!- my grammar be! Anyways: 7/10 one away from perfectionismisticisms...
