Also, I absolutely love the idea of Squibs being used as groundskeepers, house keepers, whatever-keepers. Because Squibs are like Muggles and have no power, but they're still privy to Wizarding secrets so the Wizards don't have to hide anything and they can also pat themselves on the back and feel like they've done a Good Deed by hiring an otherwise unemployable Squib that would otherwise have to work in a... Muggle occupation ;^(((((
