Harry did not usually lie in bed reading his textbooks; that sort of behaviour, as Ron rightly said, was indecent in anybody except Hermione, who was simply weird that way.

The passage treats reading textbooks in bed as almost improper, then exempts Hermione by calling her unusual. That reversal makes diligence the comic exception to an informal rule. The judgment reveals the perspective of less enthusiastic readers as much as it describes her habits.
