Hermione Jean Granger was a creature of habit.
Her alarm clock rang every morning at 6:04 A.M., a perfectly reasonable time that made her feel as though she was luxuriously sleeping in. This was followed by some hot water with a squeeze of lemon juice, ten minutes of stretching like her elderly cat, a five-and-a-half minute shower, and a bowl of muesli.
This routine was necessary if she was to arrive at her office at the Ministry each day at 7 o'clock on the nose.
There was time for a coffee on the way.
