'What if today was your last day?'
Nickelback – If Today Was Your Last Day
Argus Filch had always loved clean. He'd loved clean and he'd loved cleaning. He'd rather enjoyed taking the time to turn a filthy, nigh uninhabitable room into a place where people loved to be. He supposed he'd liked standing back when he was done and knowing that he'd done something worthwhile. That he'd somehow made a difference to someone's day.
It was much the same when he became caretaker at Hogwarts School of Witchcraft and Wizardry. He liked to know that Hogwarts was neat and orderly. He wanted the students to learn the importance of respecting their environment. None of this running around throwing spells around in the hallways, throwing Dungbombs and generally causing mayhem. It frustrated him that the students refused to learn what was good and right and what wasn't.
But one day – one day – they'd understand. He'd make sure of it.
