Harry Potter: 10 Worst Things Hermione Has Ever Done

10. Acted Like A Bossy Know-It-All

It’s easy to forget just how annoying Hermione was at the start of Harry’s first year.

Determined to prove how intelligent she is, Hermione acts like a bossy know-it-all who’s obsessed with following rules. Whilst this does lead to a fair amount of humour – particularly when Ron’s involved – Hermione’s sanctimonious demeanour is infuriating for a large chunk of The Philosopher’s Stone.

‘… you mustn’t go wandering around the school at night, think of the points you’ll lose Gryffindor if you’re caught, and you’re bound to be. It’s really very selfish of you.’

The moment she arrives at the castle, Hermione is desperate to win over the teachers and prove how clever she is. There’s nothing wrong with being enthusiastic about school, but when enthusiasm bubbles over into arrogance, it isn’t pretty. Thankfully, Hermione grows out of her annoying attitude fairly quickly.
