there are two types of people
- those who say that LOST is stupid and made no sense and wont shut the fuck up about the god damn polar bear
- those who actually watched the series from start to end
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.
Peter being overly enthusiastic about being asked to do it, and slapping Lily in the face by accident.
