Sirius Black high-fiving Lily Evans every time she raises her hand in class.
Sirius asking James to high five her when he is too sick to come to class.
Remus Lupin doing it with a sigh and an immediate apology when neither Sirius or James is available.

story featuring a city where it’s cloudy and rains almost all the time but instead of being stereotypically gloomy and grim, it’s lively and colorful and people party hard indoors and decorate the streets with colorful strings of lights. umbrellas are major fashion accessories and nobody is caught dead without one. festivals are all held indoors except for rain parades. everyone has massive gardens. its awesome.
